[Dovecot] 1.0alpha3: assert and core

Tue Oct 18 17:54:51 EEST 2005

Hi,

An assert and core with 1.0alpha3 on Solaris 9, mbox format,
imap only, compiled with gcc 4.0.1.  The syslog message was:

imap(user): file message-body-search.c: line 393 
(message_body_search_ctx): assertion failed: (input->v_offset <= 
part->physical_pos)

gdb core dump analysis is attached.
