# dovecot --version 0.99.12

# tail /var/log/mail.log ... Jan 6 16:56:55 gecko dovecot: child 16505 (imap) killed with signal 11 ...

When I use squirrelmail, the imap process always segfaults when I try to enter my INBOX group. Squirrelmail produces the following error message:

ERROR : Connection dropped by imap-server.
Query: EXPUNGE

When I use gnus, I can enter the group just fine, but gnus/emacs hangs on exit (100% reproducible, as is the squirrelmail case). Turning on debug info I catch this in the imap log:

37 UID SEARCH UID 1098 NOT SINCE 30 DEC 2004

• SEARCH 37 OK Search completed. 38 EXPUNGE read:errno=0 (hangs until emacs is killed)

So in each case, it seems to happen on EXPUNGE. I got it to produce a core file, and this is the backtrace:

(gdb) where #0 0x08071a58 in mail_index_lookup_field_raw () #1 0x080666b6 in mbox_mail_get_location () #2 0x08063111 in mbox_is_valid_mask () #3 0x08063553 in mbox_expunge_locked () #4 0x0806a9c3 in index_storage_expunge () #5 0x08051cc6 in cmd_expunge () #6 0x08054ae9 in _client_reset_command () #7 0x08054b78 in _client_input () #8 0x0808b108 in io_loop_handler_run () #9 0x0808aa98 in io_loop_run () #10 0x0805ac29 in main ()

Please let me know if I can provide any further information. I don't subscribe to the mailing list, but I'll try to keep up on the archive in the next few days.

Thanks, Tom
