# This file implements regression tests for SQLite library. Specifically, |
# 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. |
