I would like to propose we backport ast_register_cleanup, use that to register format_attr_shutdown.  I meantioned this on #asterisk-dev last week, Matt said he could go for this approach if it's the best way to resolve this issue.  I've posted the patch to ASTERISK-23103.  I've tested with and without the patch, I'm unable to reproduce the crash with the patch.
