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 : #2 0x2833386a in abort () at /usr/src/lib/libc/stdlib/abort.c:65 : #3 0x282b7113 in arena_dalloc_bin (arena=0x8049c60, chunk=0x28800000, ptr=0x28900e60, mapelm=0x28800c14) at /usr/src/lib/libc/stdlib/malloc.c:2570 : #4 0x282b8bfa in idalloc (ptr=0x28900e60) at /usr/src/lib/libc/stdlib/malloc.c:4302 : #5 0x282b9b7a in free (ptr=0x28900e60) at /usr/src/lib/libc/stdlib/malloc.c:6132 : #6 0x2832e53b in __clean_env (freeVars=true) at /usr/src/lib/libc/stdlib/getenv.c:236 : #7 0x282631d0 in ??
