[asterisk-bugs] [JIRA] (ASTERISK-21693) Use of possibly uninitialized value in ast_channel_hangupcause_hash_set

[John Hardin (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-21693?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=207223#comment-207223 ] 

John Hardin commented on ASTERISK-21693:
----------------------------------------

This may be a broader issue, as there are several places where the data structure is allocated with ast_malloc or ast_alloca, but emulate_sip_cause is not initialized.
