dovecot - Jun 2008 - While searching: Assertion failed (offset >= ctx->input->v_offset)

Hi,

while a user is searching through his (1.2 GB, >150000) mails, I get a lot of
these messages in the log, and the search (with Thunderbird) doesn't finish:

Jun 19 14:35:45 stshamail1 dovecot: Panic: IMAP(username): file 
message-parser.c: line 620 (preparsed_parse_body_init): assertion failed:

Jun 19 14:35:45 stshamail1 dovecot: child 30070 (imap) killed with signal 6

What's wrong here? How to proceed with debugging?

Thanks,
Patrick.

What Dovecot version? (Didn't I fix this a few weeks ago?)

Did you test it without index files? I couldn't reproduce the crash. Do
you use 32bit or 64bit Dovecot?
