12: # it tests that ticket [80ba201079ea608071d22a57856b940ea3ac53ce] is
13: # resolved. That ticket is about an incorrect result that appears when
14: # an index is added. The root cause is that a constant is being used
15: # without initialization when the OR optimization applies in the WHERE clause.
