I've seen perl core dumps a few times too. They seem to be triggered by
Gnome bug-buddy, but I haven't had much time to investigate why/when
they are triggered. A typical Perl traceback here looks like this:
: (gdb) bt
: #0 0x28334d77 in kill () at kill.S:3
: #1 0x28239017 in _raise (sig=6) at /usr/src/lib/libthr/thread/thr_sig.c:185

: Previous frame inner to this frame (corrupt stack?)
: (gdb)
This isn't very helpful for *all* Perl core dumps, but it may lead
someone towards obtaining a better traceback...
