If you can boil the problem down to a small reproducible test
case you can probably post it to comp.lang.perl.something and
someone will probably notice it.  Or failing that some perl
devel list will do.

A few years ago I thought up a really hairy regular expression
that crashed perl, posted it to clpm and it was fixed in a couple
of hours!
