Any thoughts on this Timo? Just wondering if you were able to reproduce
the problem and saw the same behavior. We can look into it more if need
be, but since I can replicate it on both Fedora and Solaris, I'm
guessing it's a fundamental bug with how certain malformed emails are
searched.
Thanks,

Unfortunately, the patch didn't help, BUT I've discovered some very
interesting things along the way that I think you'd like to hear:
1) The problem stems from certain emails with odd or badly formed
characters.
The reason I wasn't seeing it on one machine was because I was using a
different folder to test with. Once I moved over that folder the same
issue occurred. This got me thinking...
2) This is *not* a localized Solaris issue, I can replicate the
problem on my Fedora 10 i386 workstation with the stock F10 1.1.10
package.
On Linux at least for me), however, it doesn't grow and grow, it just
dies and core dumps immediately once it hits an email it doesn't like:

Here is the backtrace from Fedora 10:

To help you out I'm going to give you the email folder that I have
been using to replicate this. It's just a maildir format spam folder,
so no sensitive emails... just lots and lots of junk. =) You should be
able to replicate it without a problem.

Attached patch probably helps?
