I'm sorry to say that for some reason I am having real trouble getting a core dump on one of our mail systems. It's running CentOS 5, and as far as I know I haven't forgotten anything - set the 'ulimit', and set the suid_dumpable to 2; restarted exim. I assume the core would be somewhere in the /var/spool/exim directory. I have just set suid_dumpable to 1 to see if that helps. I have applied the above patch to another of our systems to see if the segfaults stop. One thing I am a bit confused about is that we have 3 mail systems, but only the two virtual ones are seeing this fault. The remaining physical server has not had any segfaults. I would have expected to see segfaults on all three systems.
