Hi everyone,
I'm trying to upgrade/test our configuration files from Dovecot 1.2 to 2.0.11. I used the Dovecot config convert command, created a RHEL 5 x86_64 rpm, and tested it. I can connect, but once I login, the IMAP service segfaults. I've also reproduced this on version 2.0.8.
I installed the debug RPM (for the stripped symbols), took a look at the core dump in gdb, and just got the _start method in ld_preload and a broken pointer in the backtrace. I tried to strace everything but the segfault doesn't happen then :-). I'm not sure what to do to get better information.
I attached my client session, dovecot -n output, gdb trace, maillog, and the core dump.
I published the RPMs I made at:
http://c3205012.r12.cf0.rackcdn.com/dovecot-2.0.11-1_125.x86_64.rpm
http://c3205012.r12.cf0.rackcdn.com/dovecot-debuginfo-2.0.11-1_125.x86_64.rpm
My platform is RHEL 5 with kernel 2.6.18 on x86_64.
Is there anything else I can provide for more info?
Thanks,
Nick
