DB2 FOR LUW / DB2FORLUW / A50 - DB2

Under rare scenarios, DB2 might abend if the following 
conditions are true: 
 
1) The query contains one or more GROUP BY clauses. 
2) The number of grouping columns in the GROUP BY exceed the 
number of output columns. 
3a) The subselect containing the GROUP BY is a parent to an 
existential subquery. 
 
OR 
 
3b) The subselect containing the GROUP BY is joined with another 
subselect containing a DISTINCT clause.
