There are instructions for getting a backtrace here:

Soooo ... I've recompiled mod_perl with MP_DEBUG=1 and I've got some
core dumps. I'm hoping I don't need to recompile perl because I'm
using debian, and perl and debian are so closely intertwined that that
could be tricky.
Here's my backtrace, any ideas?
