[Dovecot] dovecot-1.2.8 imap crash (with backtrace)

[David Halik]

I found this post from a couple of weeks ago:

http://www.mail-archive.com/dovecot@dovecot.org/msg24127.html

Any update on this? I'm experiencing the same issue. Out of a user 
population of 4000, I get about 20 of these dumps a day, so it's not 
major issue, but I thought I'd follow up.

Here is an example:

http://pastebin.com/f29c55de5

I can provide a more detailed debug log from teh core dump if necessary, 
but since the above email already had it I figured I'd wait.

Note this is *not* the same issue as:

     - maildir: v1.2.7 and v1.2.8 caused assert-crashes in
       maildir_uidlist_records_drop_expunges()

I applied those patches to my 1.2.8 installation before 1.2.9 was 
released and that immediately fixed the expunge crash, but the 
array_delete bug is still there.
