# Test for %fast-slot-ref, which was previously implemented such that | |
# an out-of-range slot index could escape being properly detected, and | |
# could then cause a segmentation fault. | |
# | |
# Prior to the change in this commit to goops.c, the following | |
# sequence reliably causes a segmentation fault on my GNU/Linux when | |
# executing the (%fast-slot-ref i 3) line. For reasons as yet | |
# unknown, it does not cause a segmentation fault if the same code is | |
# loaded as a script; that is why we run it here using "guile -q <<EOF". | |
exec guile -q >/dev/null 2>&1 <<EOF | |
