Repository: Asterisk


Description
-------

This small change is intended to address a crash seen in the testsuite, 
specifically with the PJSIP qualify test.

In that test, when Asterisk shuts down, sorcery kills its wizards container 
along with its sorcery instance container. After this occurs, a scheduled 
qualify is triggered, which attempts to use a freed wizard, therefore causing a 
crash. The reason for this is that sorcery instances have a bare pointer to a 
wizard (through an intermediary ast_sorcery_object_wizard struct). When the 
container of wizards is freed, the pointer on the sorcery instance is left 
dangling.

This patch addresses the problem by keeping wizards alive as long as a sorcery 
instance has a reference to the wizard.

Testing
-------

This change makes the PJSIP qualify test go from crashing 1 in 5 runs to 
running 120+ times with no crashes.


Thanks,

Mark Michelson
