| Problembeschreibung: |
When the following conditions are all met, compiling a query or
modifying statement may trap with stack:
sqlnq_qtboprparent::op
sqlnq_mch::is_maximal
sqlnq_som::compute_matchinfo_opt
sqlnr_compute_matchinfo
sqlnr_optprep
sqlnr_optprep_action
(1) There are at least two replicated MQT (Materialized Query
Table) and at least one non-replicated optimizer MQT or
statistical view. An optimizer MQT is such MQT whose definition
