# it tests that ticket [80ba201079ea608071d22a57856b940ea3ac53ce] is
|

# resolved. That ticket is about an incorrect result that appears when
|
||||
# an index is added. The root cause is that a constant is being used
|
||||
# without initialization when the OR optimization applies in the WHERE clause.
