Asterisk 1.6.2.18, 1.6.2.18.1, 1.6.2.18.2 Crash With Microsoft Exchange Unified Messaging

We use Unified Messaging to provide mailboxes to our users in Asterisk along with the added features UM provides over the built in Voicemail app, and we recently upgraded from 1.6.2.11 to 1.6.2.18 and found a new bug.  The bug was introduced in 1.6.2.18, and is fixed in the asterisk 1.6.2 branch in SVN as of 6/29/2011.  The 1.6.2.19-rc1 tag has the fix included as well, so be sure to use that if you are planning to use Exchange Unified Messaging with Asterisk.


Example:

    -- Called 1593@Exchange2010LCYEX2
Segmentation fault (core dumped)

I didn't bother to do much investigation considering the fix is included in 1.6.2.19-rc1.
