> Key: TRAFODION-2761

> Project: Apache Trafodion
> Issue Type: Bug
> Components: sql-cmp
> Affects Versions: 2.0-incubating
> Reporter: Hans Zeller
> Assignee: Hans Zeller
> Fix For: 2.3-incubating
>
>
> TMUDFs have the ability to eliminated unneeded columns, both in their result
> and in their child table. However, when we eliminate all columns in the child
> table, I have been seeing core dumps, as we dereference some data structures
> that aren't there in that case. Sorry, I don't have a good and easy test case
> at the moment, but I have been able to identify the problem spots and code a
> fix.
