| Description: | This was caught by the Asterisk Test Suite during the bridges/blind_transfer test:
https://bamboo.asterisk.org/bamboo/browse/AST-ATSARI-90 When ARI attempts to unsubscribe from the {{last_bridge}}, it crashes as it has a stale pointer to the bridge. This is something of a fundamental problem with how we're managing subscriptions to things that ARI doesn't own. The bridge, in this case, can get destroyed at any point: that destruction message *must* tear down the subscription at the same time. A control structure should almost certainly not have a reference to any object that it doesn't own. Backtrace is attached to this issue. | ||
