Hi,
I've recently started using dovecot-lda to handle my local maildir
deliveries from Exim. Unfortunately I've been experiencing the
occasional failed delivery - My Exim logs were showing:
Child process of virtual_dovecot_delivery transport (running
command "/usr/local/libexec/dovecot/dovecot-lda -d $local_p...@$domain
-f $sender_address -a $original_local_p...@$original_domain") was
terminated by signal 11 (Segmentation fault)
I originally thought a specific mail was causing the crash, but
calling the command myself delivered the mail without any issues.
However, I found if I ran a script that delivered the same mail 10
times, I could reliably cause multiple segfaults all with the
following backtrace:
#0 0x005581e9 in maildir_sync_set_new_msgs_count (ctx=0x0, count=1)
at maildir-sync-index.c:50
No locals.
#1 0x0055f3c0 in maildir_save_move_files_to_newcur (_ctx=0x85afe60)
at maildir-save.c:857
files = {arr = {buffer = 0x8555a08, element_size = 4}, v =
0x8555a08,
v_modifiable = 0x8555a08}
mfp = 0x8555a2c
new_changed = false
mf = 0x85affa8
newdir = true
[...]
Any ideas?
Yes, this was reported several times already. First thread:

Apply this change:
http://hg.dovecot.org/dovecot-2.0/rev/e2f9baa436f2
That should fix it.

Stephan.
