This is a multi-part message in MIME format.Hello,

I don't believe this bug has been reported here yet.

A few weeks ago, Luke Gorrie and myself had fun investigating a segfault
in GC64 mode. The fix has been committed to RaptorJIT[1] and OpenResty's
fork of LuaJIT[2].

Attached are two patches: the fix itself and the test case committed to
luajit2-test-suite[3].

We hope that this patch makes it way upstream or into other existing
forks out there.

Cheers,
Thibault
