[asterisk-bugs] [JIRA] Commented: (ASTERISK-20515) core dump in ast_channel_destructor if chan->tech_pvt is not null

[Joshua Colp (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-20515?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=197987#comment-197987 ] 

Joshua Colp commented on ASTERISK-20515:
----------------------------------------

Going down this rabbit hole more - the code present there is a "worst case stab" approach to get rid of the tech_pvt. It is your responsibility in the hangup callback (or elsewhere, depending upon channel driver design) to set it to NULL and ensure it gets freed in the implementation specific manner.
