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

[Dade Brandon (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-24925?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=226091#comment-226091 ] 

Dade Brandon commented on ASTERISK-24925:
-----------------------------------------

as a side note, all ast_rtp_instance_set_read_format and ast_rtp_instance_get_stats crashes have instance->engine === NULL and are a null pointer dereference

LEt me know if you feel any group of these should be filed as a separate bug report, but given that it all started after our WebRTC migration, I'm suspecting it is a memory corruption somewhere causing all of these crash locations.

> Will try to debug this issue myself first, and add more data  continuously.
