dbmail 2.0rc2 segfaults on my dual opteron system. I've tried using both MySQL
and PostgreSQL to see if it was something tied to a particular RDBMS backend,
but that doesn't seem to be the case.
dbmail-smtp segfaults as soon as it hits an empty line (the break of the header
from the message body) when dbmail is trying to deliver to a local user's
mailbox.
I've included backtraces from both mysql and postgresql. Looks like something
messes with the header pointer to me. I tried tracking it down but wasn't able
to put enough time into it. I hope this may give those of you who know the code
better an idea of what might be happening. If you need more information let me
know.
