dovecot - Jan 2007 - RC18 core dumps

Still seeing a few core dumps via the deliver process and corrupted
transaction log files with RC18:

Jan 22 10:46:36 zahara deliver(user at host.com): Corrupted transaction log
file /data/mail/host.com/us/user at home.com/dovecot.index.log: start_offset
(71680) > file size (71520)
Jan 22 10:46:36 zahara deliver(user at host.com): seq = 6, rec->uid = 0,
first_new_seq = 6, records = 5
Jan 22 10:46:36 zahara kernel: pid 41186 (deliver), uid 127: exited on
signal 6 (core dumped)

Jan 22 10:50:17 zahara deliver(user at host.com): Corrupted transaction log
file /data/mail/host.com/us/user at host.com/dovecot.index.log: Append with UID
512, but next_uid = 513

However, if the user gets another email, it appears deliver doesnt core dump
again.

Thoughts?

Dean, do you see this before the below error too?

Is it only deliver that crashes with this error, or does imap too?

The easiest way for me to debug this would be if I could examine the
core file myself with gdb. If the core file doesn't contain anything too
secret (you could check with eg. strings), could you send me the core
file and the deliver binary that produced it?

Although I don't know how well gdb handles other OSes binaries. I can at
least debug Linux/x86/x86_64 and Solaris/Sparc binaries.

If I can't directly check the core file's contents, I'll try adding
more
asserts to catch this bug earlier so I could figure out what's causing
it..
