Does this still happen with the latest CVS sources?

Does anyone on this list use FreeBSD 6.2, and is able to reproduce
this?

Does anyone know if the FreeBSD is still using GCPRO's?  If so, could
someone check Flookup_key for missing GCPRO's?

I could not find any GC problems in Flookup_key.  Both access_keymap and
get_keymap properly protect their arguments as necessary.

The stack backtrace he posted shows the use of mark_maybe_object, so it
seems that GCPRO's aren't used here.
