I've got a perl script which dumps core right after it runs. I'd like to isolate the conditions better, so that I can submit a bug report via perlbug. However, this bug is proving difficult to track down. For example, all of the following things seem to make the bug disappear: This bug seems to occur in both perl5.8.4 and 5.8.3, running under HP/UX.

My question: can anyone think of a good way that I can try to track this bug down?

The script is about 1800 lines, and references about 13 different perl modules. Some of those modules refer to other modules which do contain perl XS code. Those modules do sound like a candidate for a coredump.

On the other hand, there's a bug in perl5.8 that we know causes coredumps on our platform. However, that bug was caused by asking perl to parse an invalid perl program, and was triggered during a syntax check, not after the program terminated. The new bug may/may not be related.

I'm perplexed. Any suggestions would be greatly appreciated.
