I was wondering if deleting keys while iterating over a hash was reallocating the buckets and perhaps Perl was then trying to access memory that's not there. According to Adding or removing keys while iterating over a hash, this is not the case. I can't add, but I should have no problem deleting. Both merlyn and Dominus state that. However, what's vexing about this is that it appears similar to a Perl4 issue where deleting from a hash while iterating over it was verboten. This was fixed in Perl5.

Forgetting the keys should certainly cause the code to fail, but generating a core dump? That's certainly going to cause some people to panic :)

Cheers,
