Oracle Database - Enterprise Edition - Version to [Release 11.2]
Information in this document applies to any platform.


In ORA-7445 [qeshGBYOpenScan()+4] [SIGSEGV] occurs from Select.
In we observe ORA-07445 [kghalf()+624] with stack trace
kghalf qeshGBYOpenScan2 qeshGBYOpenScan qerghFetch rwsfcd qeruaFetch subex1 subsr3
The failing query is a complex Select with subselects.
It reproduces with values for bind variables and /*+ BEGIN_OUTLINE_DATA hint,  extracted from trace file.


The problem seems to depend on usage of queries with EXISTS + OR EXISTS subqueries and DISTINCT specified in subquery.
