[asterisk-bugs] [JIRA] (ASTERISK-24925) Crash within pjprojects(libpjnath) pj_stun_session_on_rx_pkt

Dade Brandon updated ASTERISK-24925:
------------------------------------

    Attachment: add_bt.txt

In case this helps, although I don't have pjproject debug symbols on this server instance, this backtrace appears to be related.   It's in destroy_tdata which is the inline function used to release the pjproject lists, which is dependent on the same - that .next is never null - there's only two destroy_tdata calls in pj_stun_session_destroy.  I'd like to assume this is on the same sess->cached_response_list and that the corruption of this list is occurring similarly to my previous debug references, but of course this could be for the pending_request_list.   If you know of a way for me to retrieve more useful data from this core dump, let me know what commands to put in.

> Not yet reproducable. The use-case is a dial to a webrtc-peer, that is a chan_sip peer with transport wss and icesupport=yes.
> Will try to debug this issue myself first, and add more data  continuously.
