I find it interesting that when I saw this poll, I was
in the process of reviewing an
old node
of mine that mentioned one way to get 5.6 to dump core.
I've also recently discovered an incredibly effective
way to get Perl to dump core: run it on a filesystem
that's corrupted in a way that causes stuff in general
to dump core. (Perl dumps core... Emacs dumps core...
ls dumps core sometimes...)
