[jira] [Commented] (TRAFODION-2612) Internal assert in CLEANUP command in some unusual cases

    [ https://issues.apache.org/jira/browse/TRAFODION-2612?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16005423#comment-16005423 ] 

Hans Zeller commented on TRAFODION-2612:
----------------------------------------

The problem is in ExDDLwithStatusTcb::work(). We deallocate memory without setting the pointer to it back to NULL. This can cause the code to try to deallocate the memory a second time in some error cases. The result is an assert in NAMemory.

> I've seen an internal assert in a CLEANUP in the - unusual - case where the compile of the SQL command used inside gives an error.
> Example: seabase/TEST026 failure NAHeap assert during CLEANUP. This only happened with a build where I had a compiler bug that caused a failure of a compile.
