Call stack in trace file shows:

Note: A CASE statement is associated with the query in the trace associated with the error.  In this case, there was PL/SQL code associated with the execution of the SQL statement in the trace file.  The PL/SQL code contained the CASE statement but this could not be seen in the trace.



The issue can also manifest itself with this call stack:
