I think this bug is actually in the regex library, not in cyrus. I do wish 
cyrus would use PCRE if it was available though, PCRE seems much more robust 
than the GNU posix regcomp/regexec stuff. Hmmm, I just noticed "man 
pcreposix", I might look into getting cyrus to use that!

Anyway, the way I found to track down the problematic regex was to gdb the 
imapd process, and go up the stack a few times to see the pattern that was 
passed to regcomp/regexec.
