I assume that I introduced this bug, so I'm assigning it to myself.

(In [14047]) Undo, for the time being, the effects of r13887.

Those changes are supposed to exploit more cases where LOGAND and LOGIOR are applied to natural-sized operands, but the changes are buggy. See ticket:708.

  • Resolution set to fixed
  • Status changed from new to closed

Logical op improvements are improved.

This test case has been added to ccl's test suite.
