Hmmm, is it a variation on the same bug perhaps?

1.151 is the 2.2.3 release version.

Hmmm, I wanted to show that the line numbers were correct, but the
'annotate' doesn't seem to work in cvsweb...

https://bugzilla.andrew.cmu.edu/cgi-bin/cvsweb.cgi/src/cyrus/imap/mailbox.c?annotate=1.151

If I just download it instead:

https://bugzilla.andrew.cmu.edu/cgi-bin/cvsweb.cgi/~checkout~/src/cyrus/imap/mailbox.c?rev=1.151&content-type=text/plain

And go to line 2018, it seems to be the correct line number...

Was in my original post...

(gdb) p cache_ent
$5 = 1

This value seems odd though...

$3 = 4294961280
(gdb) p cacheitembegin

Isn't that (unsigned)-6016. Should this ever be negative?

(gdb) p mailbox->cache_base
$2 = 0x41456000 "A"
(gdb) p cache_offset
$3 = 4294961280
(gdb) p cacheitembegin
