      Description

      Simplification of OR expressions incorrectly loses a term. For example,

      (0 < a and a <= 10) or a is null or (8 < a and a < 12) or a >= 15

      is simplified to

      as is null or (0 < a and a <= 10) or (8 < a and a < 12)

      (Moving a is null to the front is expected, but removing a >= 15 is wrong.)
