Stefan Engström commented on ASTERISK-23319:
--------------------------------------------

Unfortunately this crash has NOT happend again in the last week despite robots calling the queue with queue-timers.

Moreover, unfortunately the one crash was done on an asterisk-13.1.0 with a few custom small patches applied to it. I did find the crash-log and I cannot see how this crash could not have happend with untouched asterisk-13.1.0-code as the patches does not really alter logical flow. I attach those patches too but note they are not code contributions, they are just old patches applied to a special installation. 

What is the real possible harm in putting a qe.pr=NULL; in the leave_queue code? (cf mjordans post)
