DB2 FOR LUW / DB2FORLUW / 970 - DB2

DB2 may terminate abnormally upon detecting memory corruption. 
This can happen if the query is complex with numerous tables and 
local range predicates. The problem does not happen if there is 
no local range predicate in the query. 
The stack trace might look as follows:
