cfallin opened PR #11511 from cfallin:fuzz-exceptions to bytecodealliance:main:

This pulls in Alex's patch from here as the first commit, and an update to DiffValue comparison to support exnrefs as the second commit.

I've fuzzed locally with differential and (i) found the exnref comparison that led to the second commit, so I know that this is doing "something", and (ii) hit a segfault in V8 on a divide-by-zero, so that's a thing but I think not my thing.

Fixes #11485.

cfallin commented on PR #11511:

Test failures seem to be unrelated, from a new nightly warning perhaps (?) -- cc @alexcrichton on this ?
