dovecot - Nov 2004 - 1.0-test53, sig11 when sorting by thread

Hello.

When trying to sort a folder by thread (with pine4.61), I get a sig11. 
The mailstore is Maildir, indexes stored in /var/indexes/%u.

The syslog on the server shows this:

Nov 29 11:37:55 olan dovecot: IMAP(kowalski): Corrupted index cache file
/var/indexes/kowalski/.INBOX/dovecot.index.cache: record points outside file
Nov 29 11:37:56 olan dovecot: child 14344 (imap) killed with signal 11

A backtrace of the core is attached.

Thanks.

PS: I tried with mbox mailstore, and got the same sig11.

I think the cache file format changed a bit. The crash is fixed in CVS, 
but you should be able to fix it just by deleting the cache file? Hmm. 
Although I think it should have deleted itself above and retrying 
should have worked..

I deleted the cache file, without success. I just tried with the latest 
nightly snapshot, and it still crashes.

For the CVS version, I am not able to build it; running autogen.sh on my 
system (debian woody) gives a lot of undefined macros errors. I must be 
missing something...

Deleting cache files did not help on this issue, latest CVS code
works.

CVS lists this as first line of configure.in:
AC_INIT(dovecot, 1.0-test52, [dovecot at dovecot.org])

and can't find these symbols at link time:

file_cache_free
file_cache_get_map
file_cache_invalidate
file_cache_new
file_cache_read
file_cache_set_fd
mail_cache_expunge_handler
mail_cache_sync_handler
