[asterisk-bugs] [JIRA] (ASTERISK-21696) Assertion error results in crash in pjproject's ICE worker thread

[Pedro Howat (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-21696?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=210821#comment-210821 ] 

Pedro Howat commented on ASTERISK-21696:
----------------------------------------

This is in no way a fix for this but I was able to prevent these crashes with no apparent side effect by simply commenting the assertion in pjlib. I'm using this patch until I can dig into this code a little deeper and understand the real issue.
