[Dovecot] alpha5: assert and core

Mon Dec 19 15:54:39 EET 2005

My setup:  Solaris 9, dovecot built with gcc 4.0.2.  Mailboxes on
remote NFS file mount from another S9 box (mbox format), index files 
local disk.  IMAP usage only.  Dovecot build like so:

VERSION=1.0.alpha5
CC=gcc CFLAGS="-g -O" CPPFLAGS=-I/opt/openssl/include \
LDFLAGS=-L/opt/openssl/lib \
./configure --prefix=/opt/dovecot.$VERSION --with-ssl=openssl \
--with-ssldir=/opt/openssl/ssl  > configure.out

The assertion:

Dec 16 14:59:54 emerald dovecot: [ID 107833 mail.error] imap(user): file message-body-search.c: line 414 (message_body_search_ctx): assertion failed: (input->v_offset == part->physical_pos + part->header_size.physical_size)
Dec 16 14:59:58 emerald dovecot: [ID 107833 mail.error] imap(user): file message-body-search.c: line 414 (message_body_search_ctx): assertion failed: (input->v_offset == part->physical_pos + part->header_size.physical_size)

(twice in four seconds).  The gdb traceback and core dump analysis
is attached.  This is the only core from alpha5 in about a week's
worth of production usage.
