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

[Bob Stine (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-20515?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=198043#comment-198043 ] 

Bob Stine commented on ASTERISK-20515:
--------------------------------------

The problem that I reported occurred in an error handling block.  Action taken by the block is, as far as I can tell, guaranteed to cause a core dump.  Unintentionally dropping core strikes me as a bug.

Logging a strident warning, asserting that the value should be null, etc., would be better than trying to free a block of memory when that just won't work.
