Asterisk 1.8.1.1 will crash when MixMonitor()ing and then trying to use Swift.

asterisk will crash after printing to the console that is about to say "after" with swift.

This crash is in app_swift.  Since that module is not distributed with Asterisk, we do not support it.

Sorry to reopen, but can you confirm that this issue is not simply https://issues.asterisk.org/view.php?id=16196 which might not have made it into 1.8 ?

This made it into 1.8 because it was merged into trunk (which 1.8 was branched from).
