Author: mjordan Date: Wed Apr 8 21:03:57 2015 New Revision: 434448 URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=434448 Log: apps/app_queue: Prevent possible crash when evaluating queue penalty rules
Although it only occurred once, a crash occurred when a queue attempted to evaluate a queue penalty rule that appeared to have already been destroyed. In many locations in app_queue, a test is done to see if qe->pr is NULL; however, when we dispose of a queue's penalty rules, we don't set the pointer to NULL after free'ing it. This patch does that to prevent any dangling pointers from lingering on the queue object.
