[asterisk-commits] mmichelson: branch 1.4 r92202 - /branches/1.4/apps/app_queue.c

[SVN commits to the Asterisk project]

Author: mmichelson
Date: Mon Dec 10 10:29:44 2007
New Revision: 92202

URL: http://svn.digium.com/view/asterisk?view=rev&rev=92202
Log:
If there are no members in a queue, then the loop where the datastore for detecting
duplicate dialed numbers will be skipped, meaning the datastore isn't created. This means
that when we try to free it, there's a crash. This stops that crash from occurring.

(closes issue #11499, reported by slavon, patched by eliel)
