Symptoms

When using eg. SQL Access Advisor for index analysis, the following error is raised:

ORA-600: internal error code, arguments: [qsmmixSetCkyVir-1], [], [], [], [],

The failing statement is a SQL tuning task similar to:

DECLARE
ename VARCHAR2(30);
BEGIN
ename := dbms_sqltune.execute_tuning_task(
'SYS_AUTO_SQL_TUNING_TASK');
END; :mydate := next_date; IF broken THEN :b := 1; ELSE :b := 0; END
IF; END;

And the call stack is similar to:

... qsmmixSetCkyVir qsmmixSetKkotbixt qsmmixReturnCandToO qsmmixOptimizerGenIdxCand qsmmixOptimizerSetupIdxCand ...
