Bugs: ASTERISK-23103
    https://issues.asterisk.org/jira/browse/ASTERISK-23103


Repository: Asterisk


Description
-------

Backport ast_register_cleanup, use it for format_attr_shutdown to ensure that format interfaces container is not cleaned during non-graceful shutdown.

  /branches/11/include/asterisk.h 410826 

Diff: https://reviewboard.asterisk.org/r/3376/diff/


Testing
-------

I verified after applying this patch I am unable to cause a segfault by running 'killall asterisk' while a call is active.  This test causes a SEGV every time without the patch.


Thanks,

Corey Farrell
