[asterisk-bugs] [JIRA] (ASTERISK-23103) Crash in ast_format_cmp, in ao2_find

[Corey Farrell (JIRA)]

     [ https://issues.asterisk.org/jira/browse/ASTERISK-23103?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Corey Farrell updated ASTERISK-23103:
-------------------------------------

    Attachment: format-shutdown-segv.patch

find_interface does not check for interfaces==NULL, causing ao2_find to segfault when called after format_attr_shutdown. This happens when shutting down fast with active channels.

> I am seeing a crash in ao2_find in the ast_format_helper function.  It's possible this is related to ASTERISK-22875.
> It's possible that this is related to the addition of SIP_CODEC_INBOUND and SIP_CODEC_OUTBOUND to the dialplan.
