[Dovecot] dovecot-auth core dumps

[Cassidy B. Larson]

Seeing a few core dumps on my two proxy servers with dovecot-auth since
upgrading to 1.0.2.

Example:
Jul 30 13:36:51 alora kernel: pid 20234 (dovecot-auth), uid 0: exited on
signal 11 (core dumped)
Jul 30 13:36:51 alora dovecot: child 20234 (auth) killed with signal 11

Jul 29 19:17:08 marbella kernel: pid 70627 (dovecot-auth), uid 0: exited on
signal 11 (core dumped)
Jul 29 19:17:08 marbella dovecot: child 70627 (auth) killed with signal 11

Running:
FreeBSD 6.1 i386
Dovecot 1.0.2

I'm not proficient in running 'gdb', so I followed the instructions from the
wiki for a full backtrace. Output is below. Is there anything else I should
be looking for, or any other commands I should send to gdb?

Thanks,

Cassidy
