    Description

      https://github.com/ursacomputing/crossbow/runs/1877315066#step:6:2818

      Comparison kernels generate an output bitmap for all array values, including those masked by a null bit. This should be fine since the indeterminate bits are also masked in the output but valgrind still triggers on the branching in GenerateBitsUnrolled.
