I am working on implementing support of the ECMAScript 2015 static modules in a .NET library ([JavaScript Engine Switcher](https://github.com/Taritsyn/JavaScriptEngineSwitcher) project). I've already read the [API documentation](https://github.com/microsoft/ChakraCore/wiki/JavaScript-Runtime-%28JSRT%29-Reference) and [“Steps needed for es6 modules embedding ChakraCore”](https://github.com/Microsoft/ChakraCore/issues/4324) discussion.
But I have not found anywhere information about how to get the result of module evaluation. Suppose there is the following code of root module:
```js
import * as geometry from './geometry/geometry.js';
new geometry.Square(15).area;
```
The expected result of evaluating this module is a numerical value equal to `225`, but the [`JsModuleEvaluation`](https://github.com/microsoft/ChakraCore/wiki/JsModuleEvaluation) method always returns `undefined`.
To make it easier for you to find the reason for this behavior, I created a [.NET Core console application](https://github.com/Taritsyn/TestChakraCoreEsModules).

Consider implementing top-level await, stage 3: https://github.com/tc39/proposal-top-level-await
I had misgivings about this, but it seems to have picked up traction recently and is already stage 3 so I doubt it's going anywhere, regardless of what I think of it. 😛

Module execution of ES modules is based on post-order execution up the graph (with circular deduping).
The Edge behaviour is incorrectly implementing a _reverse post-order execution_.
The simple example of this is the following:
```html
<script>order=[]</script>
<script type="module">
import '/a.js';
import '/b.js';
console.log(order);
</script>
```
where `a.js` contains `order.push('a')` and `b.js` similarly.
where edge will execute `b` and then `a`, instead of `a` and then `b`!
The fix should be simple (one loop can just be reversed somewhere), but this is a really important bug to fix as many projects will write code like the following:
```js
import 'polyfill';
import 'stuff-that-needs-polyfill';
```
and without these guaranatees those code paths break down.
I would highly recommend marking this as an urgent priority.

Alignment hint to `v128` stores appears to affect the array index into which values get stored:
```
$ cat align.wat
(module
(import "dummy" "memory" (memory 1))
(func
(export "store_i32")
(param $index i32)
(param $value i32)
(i32.store align=4 (get_local $index) (get_local $value))
)
(func
(export "store_v128")
(param $index i32)
(param $value i32)
(v128.store align=4 (get_local $index) (i32x4.splat (get_local $value)))
)
)
$ cat run.js
const memObj = new WebAssembly.Memory({initial:1});
const module = new WebAssembly.Module(readbuffer('align.wasm'));
const instance = new WebAssembly.Instance(module, { "dummy" : { "memory" : memObj } }).exports;
let uint8_data = new Uint8Array (memObj.buffer);
print(uint8_data[0]);
instance["store_i32"](1, 0xFFFFFFFF);
print(uint8_data[0]);
instance["store_v128"](1, 0xFFFFFFFF);
print(uint8_data[0]);
$ wat2wasm --enable-simd align.wat -o align.wasm
$ ch -wasmsimd run.js
0
0
255
```
The second store should not write anything to index 0 as alignment hint, per Wasm spec, should not affect semantics of operation (can only affect its speed).

Looks like `v128` memory accesses require alignment no greater than 4, the following would fail with `align=8` or `align=16` added to `v128.load` instruction.
```
$ cat load.wat
(module
(import "dummy" "memory" (memory 1))
(func (export "test_load")
(result i32)
(i32x4.extract_lane 1 (v128.load offset=0 (i32.const 0)))
)
)
$ cat run.js
const INITIAL_SIZE = 1;
const memObj = new WebAssembly.Memory({initial:INITIAL_SIZE});
const module = new WebAssembly.Module(readbuffer('load.wasm'));
const instance = new WebAssembly.Instance(module, { "dummy" : { "memory" : memObj } }).exports;
var arr = new Int32Array (memObj.buffer);
arr[0] = 1;
arr[1] = 2;
arr[2] = 3;
arr[3] = 4;
arr[4] = 5;
arr[5] = 6;
arr[6] = 7;
arr[7] = 8;
print(instance["test_load"]());
$ wat2wasm --enable-simd load.wat -o load.wasm
$ ch -wasmsimd run.js

at Global code (/home/ppenzin/bugs/v128_alignment/run.js:16:1)
```
This is caused by using ArrayBufferView for a 4-byte type , and was introduced in 3d31f2316bfb444e932d76e0433b63deaf5f3f2f.
It felt wrong to add an ArrayBufferView for simd values (as they cannot be accessed via ArrayBuffer), I have a solution in my PR, but there might be better ways to do it.

The [documentation indicates](https://github.com/microsoft/ChakraCore/blob/c0ae3d327654e4390d9c250eb62cc81b6c47492e/lib/Jsrt/ChakraCore.h#L772) that `scriptLoadCallback` is optional (set to null if not required) for `JsParseSerialized`. This parameter is [actually checked against null](https://github.com/microsoft/ChakraCore/blob/833c7f5b862f6b56386ecff6278db64d0cdc451e/lib/Jsrt/Jsrt.cpp#L3978) and `ErrorNullArgument` is returned if it is.
Is the documentation or the code incorrect? I'm happy to fix either.

### version info
- Microsoft Edge 44.18963.1000.0
- Microsoft EdgeHTML 18.18963
### problem
In the console, if I use `await` the console generate error `Expected ';'` and refuses to run the line.
### how to re-produce
In the console.
```js
var f = async () => { setTimeout(() => { console.log('foo'); }, 1000); };
await f(); // generates "Expected ';'" error message
```

The latest version of Edge appears to have a nondeterministic branching bug.
**Background**
I have a single-page JavaScript app that works in Chrome and used to work in Edge (was working for me in July), but it is now hitting an apparent timing bug in the latest version of Edge. I'm on this version of Edge:
Microsoft Edge 44.17763.1.0
Microsoft EdgeHTML 18.17763
**Bug**
I've isolated the problem down to some simple (and expected-to-be-deterministic) string-parsing code. Basically, the code (see gist linked below) parses a line of comma-separated values, allowing values to be enclosed in quotation marks (e.g. so the values can be strings that include commas).
Now, the code itself isn't super important. What's important is that the code should produce the same result every time it runs. However, if I run this code on the exact same input in a loop, sometimes a branch will be unexpectedly taken (!!!), resulting in incorrect parsing, thus breaking my app. Note that if I turn on F12 developer tools and put a breakpoint on the unexpected branch, the issue _does not_ occur (i.e. the debugger seems to change the timing/prevent the bug from manifesting).
I have only observed this bug on Edge and I suspect it only affects the latest version of Edge (since I never hit this bug until recently and I use Edge for development). I can reproduce the bug on multiple machines (all on the latest revision of Windows 10).
**Repro**
Here is a gist that reproduces the bug (on the latest Edge only, of course):
https://gist.github.com/jaredkrinke/a1a219ed1466423e927504297d27819e
The HTML page contains all of the code. Reload the page several times and you should hit the bug (it should say "Failed after X iterations" on Edge, but it always says "Successful after 1000 iterations" on other browsers--i.e. the bug only impacts Edge).

Following code can trigger this issue.
("Illegal instruction " at ChakraCore/lib/Common/CommonPal.h:160)
```
let v2 = "Nm" && [ ];
let v0 = v3 == false;
delete v3.replace;
this.v3(true);
function v3(...v1) {
for (v0 = v2.slice([ 10061.13653 ], [ ]); v1[3] += [ "vR", v1 ]; v3[0] >>>= [ null ]) {

v2.search = v3 && [ ];
this.v3([ v3, 10846.32615 ], v2.constructor);
for (v3 = v0.replace() ? v1(v0.prototype, [ "jaQH", v0 ]) : false; v3 != ")b4="; [ ] !== v3) {

}
v0.test();
v2[true] = new Date(v1.constructor);
```
And when ch is built with `--static --sanitize=address,undefined` option it triggers undefined behaviours.

Hello,
I'm not sure if this is the correct place to raise the issue, if not could you guide me to the correct place?
I'm trying host Chakra and JScript9 JavaScript from VBA, however I'm currently having some problems with JsCreateContext() function:
```
Private Declare PtrSafe Function IECreateRuntime Lib "jscript9.dll" Alias "JsCreateRuntime" (ByVal jsRuntimeAttributes As Integer, ByVal jsRuntimeVersion As Long, ByVal JsThreadServiceCallback As LongPtr, ByVal jsRuntimeHandle As LongPtr) As Long
Private Declare PtrSafe Function IECreateContext Lib "jscript9.dll" Alias "JsCreateContext" (ByVal jsRuntimeHandle As LongPtr, ByVal IDebugApplication As LongPtr, ByVal jsContextRef As LongPtr) As Long
Private Declare PtrSafe Function IESetCurrentContext Lib "jscript9.dll" Alias "JsSetCurrentContext" (ByVal jsContextRef As LongPtr) As Long
Private Declare PtrSafe Function IEGetGlobalObject Lib "jscript9.dll" Alias "JsGetGlobalObject" (ByVal jsGlobalValueRef As LongPtr) As Long
'...
Private Function initVersion(version As String) As String
'Versions = ["IE","Edge"]
Dim hGlobal As LongPtr, sError As String, retl As Long
Select Case pVersion
Case "IE"
pHModule = LoadLibrary(DLL_JScript)
If pHModule <> 0 Then
'Create the javascript runtime... pRuntime is a global VARIANT variable at the moment
retl = IECreateRuntime(0, -1, 0, VarPtr(pRuntime))
If retl = S_OK Then
'Create an execution context
Dim ctxt As LongPtr
retl = IECreateContext(VarPtr(pRuntime), 0, VarPtr(ctxt))
'...
```
> Note: I am getting the same errors with Chakra that I'm getting with JScript9
[The full source can be found here](https://github.com/sancarn/VBA-STD-Library/blob/master/src/WIP/stdRuntimeJS.cls#L217)
The current issue is that IECreateRuntime (or internally JsCreateRuntime) is returning `65547` which I think is `JsErrorHeapEnumInProgress` (correct me if I am wrong), but I'm certainly not doing an enumeration of the heap... So is VBA internally doing heap enumerations? In which case is there a way around this? I've wondered whether I could get around this using [`HeapCreate()`](https://docs.microsoft.com/en-us/windows/win32/api/heapapi/nf-heapapi-heapcreate) and trying to create the runtime within that?
I have another theory that it may be because VBA (or EB) itself is the scripting language used in it's host, so it may be that the 2 runtimes are interfering with one another somehow?
Any ideas would be much appreciated!

Hello friends! I want to embed ChakraCore into my project.
But it's undesirable to use chakra's dll. Can I build chakra as static library(or libraries) without dll?
P.S. Chakra is better than v8, thank you Microsoft!

Consider the following program:
```
(module
(func (export "run")
(param i32)
(unreachable)
(tee_local 0)
(drop)
)
)
```
which we can embed in a script as follows:
```js
var debug = debug || (arg => console.log('-->', arg));
let buffer = new Uint8Array([ 0,97,115,109,1,0,0,0,1,5,1,96,1,127,0,3,2,1,0,7,7,1,3,114,117,110,0,0,10,8,1,6,0,0,34,0,26,11 ]);
let m = new WebAssembly.Instance(new WebAssembly.Module(buffer));
debug(m.exports.run());
```
With `ch version 1.11.9.0` I get a compile-time error:
```
$ ch chissue.js
CompileError: function run[0] at offset 36/38 (0x24/0x26): Can't tee_local unreachable values
at Global code (.../chissue.js:6:1)
```
whereas `sm`,`v8`, or `jsc` all throw a run-time error:
```
$ sm chissue.js
chissue.js line 5 > WebAssembly.Module:33:1 RuntimeError: unreachable executed
Stack:
@chissue.js line 5 > WebAssembly.Module:wasm-function[0]:0x21

global [email protected]:6:20
```
The weird thing is that Chakra's compile-time check seems to be limited to `tee_local` 😮
If we do variations that, e.g.,
- uses `set_local` instead (chissue2) or
- combines `drop` and `i32const` (chissue3)
the programs pass compile-time validation and throws a run-time error like the other 3 engines.
Variation 1 (chissue2):
```
(module
(func (export "run")
(param i32)
(unreachable)
(set_local 0)
)
)
```
```js
var debug = debug || (arg => console.log('-->', arg));
let buffer = new Uint8Array([ 0,97,115,109,1,0,0,0,1,5,1,96,1,127,0,3,2,1,0,7,7,1,3,114,117,110,0,0,10,7,1,5,0,0,33,0,11 ]);
let m = new WebAssembly.Instance(new WebAssembly.Module(buffer));
debug(m.exports.run());
```
```
$ ch chissue2.js
RuntimeError: Unreachable Code

Variation 2 (chissue3):

(drop)
(i32.const 0)
(set_local 0)
)
)
```

let buffer = new Uint8Array([ 0,97,115,109,1,0,0,0,1,5,1,96,1,127,0,3,2,1,0,7,7,1,3,114,117,110,0,0,10,10,1,8,0,0,26,65,0,33,0,11 ]);

The implementation of ‘TypedArray.prototype.fill’ in the engine is not correct. According to Ecma-262 standard, it should get the value of 'p1' firstly, and then calculate the start and end index to fill the value at corresponding items. But the actual order of implementation is reversed. The following code demonstrate our guess. The proxy ‘get’ function doesn’t run at all. JS engines like v8 & spidermonkey have different output.
The code:
```
let array = new Uint32Array(5);
let arg1 = [1, 2, 3];
let start = {
valueOf: () => {
return 5;
}
};
let end = {
valueOf: () => {
return -3;
}
};
let p1 = new Proxy(arg1, {
get: function(oTarget, sKey) {
if (sKey.toString() == 'valueOf') {
print('call valueOf');
arg1[0] = 0;
}
return Reflect.get(oTarget, sKey);
}
});
arr2 = Uint32Array.prototype.fill.call(array, p1, start, end);
print(arg1);
```
The output:
1,2,3

Running code in ch version 1.11.9.0, the output is different from other js engines.
code:
```
let val = 10;
let handler_1 = {
get: function(oTarget, sKey) {
if (sKey.toString() == 'length') {
print("in get length");
val = 1;
}
return Reflect.get(oTarget, sKey);

};
let p_1 = new Proxy({}, handler_1);
var newStr = String.prototype.toLocaleLowerCase.call({}, p_1);
print("BT_FLAG");
print(val);
```
Output of sm, v8, jsc:
```
in get length
BT_FLAG
1
```
Output of ch:
```
BT_FLAG
10
```
In the specification(https://tc39.github.io/ecma402/#sec-canonicalizelocalelist), Get(locales, “length”) shows that we can use Proxy to trap 'get length',

Upon calling `JsStopDebugging()` on shutdown with a debugger attached, I was hitting (what seemed to be) a segfault somewhere inside `ChakraCore.dll`. After compiling the engine from `master` with debug symbols, I tracked down the location of the crash to the `AssertOrFailFast` call here:
* https://github.com/microsoft/ChakraCore/blob/master/lib/Runtime/Debug/DebugContext.cpp#L359
Seems to be something to do with internal handling of generators in the debugger. As far as I can tell I'm shutting down properly, so there doesn't seem to be anything I can do to work around the issue. For now I've reverted to ChakraCore 1.11.8 which doesn't appear to have this issue.

I am learning about the bailout mechanism. I find that if the object, like JavaScriptNativeIntArray, is accessed twice in JITted code, and there is no operation that can change the type of object between these two accesses, then for the optimization purpose, the BailOnNotNativeIntArray code will only execute once.
Is there an option that can turn on all the checks in JITted code?

The class fields proposal is Stage 3 and seems to be implemented in at least V8 (Node 12, Chrome 74):
https://github.com/tc39/proposal-class-fields
It'd be awesome to have these in CC, I currently enjoy fields thanks to TypeScript, but would be awesome to be able to use them in vanilla JS too. I thought there was already an issue tracking this, but I couldn't find anything after several searches, so I'm posting a ticket now.

Simple ch based repro, the below triggers a nullptr de-reference:
```js
WScript.RegisterModuleSource("start", 'import "testXXXXa";');
WScript.RegisterModuleSource("A", 'import Default from "testXXXXb";');
WScript.RegisterModuleSource("B", 'export function notDefault () {}');
WScript.LoadScriptFile("start", "module");
```
This is an error I introduced almost a year ago without realising it whilst fixing a different issue - sorry.
If a child module (not the top parent) imports the default export from a module that is not its parent and does not have a default export this error is not detected properly and results in a nullptr de-reference instead of an error message.
I will also open a PR to fix this.

I'm not really sure if this is the place to share this. If there is a more appropriate, please let me know. Sorry in advance.
I've been working as a web developer for over a year now. Yesterday was my first time inspecting elements on Edge. And it was just terrible. I will add a GIF below to illustrate the situation. The element is a div with contenteditable. This was on my localhost. PS: I'm having normal development experience on Firefox and Chrome at the same time.
What could be happening?

The following expression, when typed into console, or as part of script:
1.4e-3 .toExponential(1)
returns value:
"1.3e-3"
expected output is:
"1.4e-3"
I have seen some other issues related to number formatting reported here, those are already fixed. However, this one is not fixed.

The `Intl.NumberFormat()` constructor of **[ECMAScript Internationalization API](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Intl)** behaves differently in:
**Microsoft Edge 41.16299.1004.0** / **Microsoft EdgeHTML 16.16299**
```javascript
new Intl.NumberFormat('de-DE', { style: 'currency', currency: 'EUR', maximumFractionDigits: 0, minimumFractionDigits: 0 }).format(8900)
"8.900 €"
new Intl.NumberFormat('de-DE', { style: 'currency', currency: 'EUR', maximumFractionDigits: 2, minimumFractionDigits: 0 }).format(8900)
"8.900 €"
new Intl.NumberFormat('de-DE', { style: 'currency', currency: 'EUR', maximumFractionDigits: 1, minimumFractionDigits: 0 }).format(8900)
"8.900 €"
new Intl.NumberFormat('de-DE', { style: 'currency', currency: 'EUR', maximumFractionDigits: 1, minimumFractionDigits: 1 }).format(8900)
"8.900,0 €"
```
and
**Microsoft Edge 44.17763.1.0** / **Microsoft EdgeHTML 18.17763**
```javascript
new Intl.NumberFormat('de-DE', { style: 'currency', currency: 'EUR', maximumFractionDigits: 0, minimumFractionDigits: 0 }).format(8900)
"8.900,00 €"
new Intl.NumberFormat('de-DE', { style: 'currency', currency: 'EUR', maximumFractionDigits: 2, minimumFractionDigits: 0 }).format(8900)
"8.900,00 €"
new Intl.NumberFormat('de-DE', { style: 'currency', currency: 'EUR', maximumFractionDigits: 1, minimumFractionDigits: 0 }).format(8900)
"8.900,00 €"
new Intl.NumberFormat('de-DE', { style: 'currency', currency: 'EUR', maximumFractionDigits: 1, minimumFractionDigits: 1 }).format(8900)
"8.900,00 €"
```
Former behaves properly, allowing to truncate fraction digits by setting the combination of `{ maximumFractionDigits: number, minimumFractionDigits: number }`, while the latter adds 2 fractional digits regardless of the config.
As for the other browsers:
**Chrome 73.0.3683.86**
```javascript
new Intl.NumberFormat('de-DE', { style: 'currency', currency: 'EUR', maximumFractionDigits: 0, minimumFractionDigits: 0 }).format(8900)
"8.900 €"
new Intl.NumberFormat('de-DE', { style: 'currency', currency: 'EUR', maximumFractionDigits: 1, minimumFractionDigits: 0 }).format(8900)
"8.900 €"
new Intl.NumberFormat('de-DE', { style: 'currency', currency: 'EUR', maximumFractionDigits: 2, minimumFractionDigits: 0 }).format(8900)
"8.900 €"
new Intl.NumberFormat('de-DE', { style: 'currency', currency: 'EUR', maximumFractionDigits: 1, minimumFractionDigits: 1 }).format(8900)
"8.900,0 €"
```
**Mozilla Firefox 66.0.2**
```javascript
new Intl.NumberFormat('de-DE', { style: 'currency', currency: 'EUR', maximumFractionDigits: 0, minimumFractionDigits: 0 }).format(8900)
"8.900 €"
new Intl.NumberFormat('de-DE', { style: 'currency', currency: 'EUR', maximumFractionDigits: 1, minimumFractionDigits: 0 }).format(8900)
"8.900 €"
new Intl.NumberFormat('de-DE', { style: 'currency', currency: 'EUR', maximumFractionDigits: 2, minimumFractionDigits: 0 }).format(8900)
"8.900 €"
new Intl.NumberFormat('de-DE', { style: 'currency', currency: 'EUR', maximumFractionDigits: 1, minimumFractionDigits: 1 }).format(8900)
"8.900,0 €"
```
|
Intl.NumberFormat() doesn't properly format numbers with "currency" style.

I couldn't find any examples of calling JavaScript functions that return promises. I'm particularly interested in how to register callbacks for resolve / reject.
We can check the state of a promise with `JsGetPromiseState` and get its result with `JsGetPromiseResult`, but I can't see how to get notified when a promise's state changes. What is the intended design, and how are others handling this scenario?
I presume we could keep a global vector on the C++ side of all unresolved promises then manually iterate over all of them on each `PromiseContinuationCallback` call, but that feels wrong (and a potential perf issue). Are there alternatives I'm missing?
Thank you!

Repro steps:
1. Go to https://console.cloud.google.com (requires a Google account)
1. Open the hamburger menu and click on the "Storage" navigation menu link
(bug occurs in minified Angular routing code)
Notes:
* Was unable to isolate the root cause so I don't have a minimum repro example
* Bug occurs in minified Angular routing code. Specifically
https://github.com/angular/angular/blob/master/packages/router/src/create_url_tree.ts#L315
which is inlined here:
https://github.com/angular/angular/blob/master/packages/router/src/create_url_tree.ts#L257.
This is minified to
```
t = {};
p = r == p.path && Jia(t, p.parameters);
```
When the bug occurs, it looks like ```r == p.path``` executes then the assignment and then
```Jia(t, p.parameters)```. ```p.paramters``` will be undefined leading to the exception.
* Bug occurs on

* Microsoft EdgeHTML 16.16299

Hello
I have validated that the test case for https://github.com/Microsoft/ChakraCore/issues/5985 runs correctly with a Debug version of ChakraCore and the small test case but there still seems to be something wrong when running against our tests and still receiving the following:
```
ASSERTION 2257: (/Users/Jimmy/websharp/projects/ChakraCore/lib/Backend/IRBuilderAsmJs.cpp, line 1044) !IsLoopBody() || offset <= GetLoopBodyExitInstrOffset()
Failure: (!IsLoopBody() || offset <= GetLoopBodyExitInstrOffset())
Illegal instruction: 4
```
Not sure how to create a small repo of this either. Is there some way to help narrow this down even further?

If a user overrides the `Symbol.toPrimitive` property of a symbol object (an object that wraps a symbol primitive), the overridden method should be called.
```
eshost -e '(() => { var s = Object(Symbol()); Object.defineProperty(s, Symbol.toPrimitive, { value: function() { return 1 } }); return s * 5; })()'
```
```js
var s = Object(Symbol());
Object.defineProperty(s, Symbol.toPrimitive, {
value: function() { return 1 }
});
console.log(s * 5);
```
```
#### ch

#### jsc

#### v8

[jsvu](https://github.com/GoogleChromeLabs/jsvu) downloads ChakraCore from GitHub releases and has used the link `osx_x64` as the operating system link 1.11.6 and previous.
Example: `https://aka.ms/chakracore/cc_osx_x64_1_11_6`
The new link for the mac os version is now: `https://aka.ms/chakracore/cc_osx_64_1_11_7`
Is there anyway we can keep these links consistent?

Why only an ExternalObject can carry a void* pointer instead of Object? When I implement a constructor function for c++ class , I need to put a c++ object pointer to js-this (which is an Object).
```javascript
let foo = new Bar();
```
```C++
JsValueRef Bar( JsValueRef callee, bool isNew, JsValueRef * args, uint16_t argc, void * data ) {
if( !isNew) { ... } // throw js exception
JsValueRef js_this = args[0]; // js_this is just an Object
// so, I can't set c++ pointer to js_this
CxxBar * bar = new CxxBar();
JsSetExternalData(js_this, bar); // Error!
JsObjectBeforeCollectCallback(.....);
}
```
Can anyone give me a good suggestion to implement the constructor of the Native class?

I've hit a bug in Edge with WebAssembly; the following code snippet:
```
static void writeTriangle(void* destination, size_t offset, size_t index_size, unsigned int a, unsigned int b, unsigned int c)
{
if (index_size == 2)
{
static_cast<unsigned short*>(destination)[offset + 0] = (unsigned short)(a);

When compiled with Emscripten to WebAssembly, works correctly in Chrome and Firefox, but doesn't work correctly in Edge - when `index_size` is 4, the code seems to still take the `if` branch instead of `else` branch (or something along these lines - I am not able to debug the resulting native code). Adding a check for `index_size == 4` to the `else` branch works around the issue.
Apologies for a somewhat high level bug report, I'm not quite sure how to reproduce this on a smaller example... The WebAssembly file in question is pretty small though.
This commit applies the workaround:
https://github.com/zeux/meshoptimizer/commit/a9d60cffcdd8bbbf0d2137861af61c620637221e
The easiest way to reproduce is to check out the parent of this commit, replace `demo/pirate.optmesh` with https://github.com/zeux/nyra/blob/master/nyra.optmesh, and open `demo/index.html` in Edge - due to CORS this needs a local web server, Python http.server will do. The mesh will be mangled due to incorrect index decoding:
Chrome and Firefox display the mesh properly:
Attached is a ,zip file with raw .wasm files before (bad) and after (good) the workaround as well as their (wasm) disassembly.

Recently you add some new code here:https://github.com/Microsoft/ChakraCore/commit/c0c3de7acdc167ca93b689f7552a5a0fe4bc8be2#diff-368bbd31c6049b4faa033bbbc971ef0f
But there are some old win10 versions that does not support cfg(my test enviroment is 10.0.14393).
And when I build ch.exe, there is a fatal error that "no such file cfguard.h" ...etc
