[asterisk-bugs] [JIRA] (ASTERISK-22126) Bridging: Memory leak for channels that hang up if they were in the bridging system

[Kinsey Moore (JIRA)]

     [ https://issues.asterisk.org/jira/browse/ASTERISK-22126?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Kinsey Moore updated ASTERISK-22126:
------------------------------------

    Description: 
What's leaking as reported by the memory allocation summary feature of MALLOC_DEBUG:
       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.
