             Summary: Bridging: Memory leak for channels that hang up if they were in the bridging system
                 Key: ASTERISK-22175
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-22175
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Core/Bridging
    Affects Versions: SVN, 12
            Reporter: Jonathan Rose


What's leaking:
       728 bytes in          7 allocations by ast_channel_get_manager_vars() line  7506 of channel.c
       728 bytes in          7 allocations by ast_channel_get_vars() line  7480 of channel.

7506: ret = ao2_alloc(sizeof(*ret), varshead_dtor);
7480: ret = ao2_alloc(sizeof(*ret), varshead_dtor);

Reproduction:
If a channel ever enters the bridging system, these two allocations will be leaked when the channel dies.

Easiest way to reproduce this is by calling bridgewait() on a channel.
Another easy method to reproduce this is to just have one device do a simple call to another.
