Commit Message:

Line 14:   * Caller is externally redirected elsewhere
Local channel optimization could also cause a channel to leave but not end the call.  The channel is swapped with the replacement caller or member channel.

File apps/app_queue.c:

PS1, Line 5921: 	RAII_VAR(struct ast_channel_snapshot *, caller_snapshot, NULL, ao2_cleanup);
              : 	RAII_VAR(struct ast_channel_snapshot *, member_snapshot, NULL, ao2_cleanup);
These RAII_VAR's are unnecessary.  There is only one return point where these variables could be something other than NULL.


Line 5928: 	if (ast_strlen_zero(queue_data->bridge_uniqueid)) {
Hmm.  handle_attended_transfer() and handle_blind_transfer() lock queue_data starting here.  They may be protecting from handle_bridge_enter() setting bridge_uniqueid.  It is strange that handle_bridge_enter() doesn't hold the lock while setting that string.

Also would need protection from handle_local_optimization_end() changing the caller_uniqueid and member_uniqueid.
