[Mimedefang] Diagnosing segmentation faults

[Nels Lindquist]

Hi there.

I'm running into an odd problem with MIMEDefang.  A particular thread 
from the SA-Talk mailing list is causing slaves to segfault (signal 
11) while all other mail traffic is flowing smoothly.  I've made no 
changes to the filter.

I set KEEP_FAILED_DIRECTORIES=yes in /etc/sysconfig/mimedefang and 
restarted the multiplexor.  After a period of time, the errors 
recurred and the four messages (one message and three replies) were 
saved as /var/spool/MIMEDefang/mdefang* directories.

I deleted the Work/ directory and tried running mimedefang.pl 
directly, which exits with "segmentation fault."

I'm not seeing any core files; how should I run gdb to get a proper 
backtrace out of this?
