Hi everyone,

the attached message does reliably crash my dovecot when trying to access a folder containing it.

Crash notice in mail.log: Apr 13 17:36:12 rafter dovecot: child 23215 (imap) killed with signal 11

My dovecot --version says: 0.99.8

Well, the version number isn't really up to date currently :) Is this CVS or -test? I don't think 0.99.8.1 yet had --version.

Has this problem been fixed in current dovecot? For now I have just quarantined the offending message but obviously I need to upgrade my dovecot soon because I don't like such kinda things to happen.

I couldn't get any crashes with it, neither with 0.99.8.1 nor current CVS. It would help if you got gdb backtrace from the crash:

Set "mail_drop_priv_before_exec = yes" in config file, so it dumps core to whatever directory you started dovecot in. Hmm. Actually I think I should change to mail root dir so it's written there..

gdb /usr/local/dovecot/libexec/dovecot/imap core bt

Or alternatively:

gdb /usr/.../imap <pid of running imap process> c <wait for crash> bt
