Summary:                    Segfault in app_voicemail, inside c-client
Description: 
I'm encountering some segfaults while running Asterisk, about 2 times a day
on a fairly low use server. It has been statically compiled with c-client.

I'm using the following versions:

Asterisk 1.4.11 (which IMAP_STORE enabled for app_voicemail)
c-client from version imap-2006k.DEV.SNAP-0709111641
I'm connecting to cyrus-imap version 2.3.8 on the same server

I should note that I've modified the app_voicemail.c file slightly, which
was necessary for use with cyrus.

After each crash, Asterisk restarts automatically (using asterisk_safe),
so the problem doesn't hold over through the restart.

I submitted this report on the imap-uw list, which contained the following
discussion, which includes output from a core dump:

http://mailman1.u.washington.edu/pipermail/imap-uw/2007-October/001705.html

I believe there's a missing initialization of vms.mailstream

A small patch is attached.

> Has applying that patch caused the crashes to stop? 

I'll be applying this patch tonight during a maintenance window.

I'll let it run for a few days and let you know how it works.
