This particular chunking eventually goes down into the following path: https://github.com/apache/arrow/blob/541cba859c3cdb4cc6cb3f456aaae79f67c7d57d/cpp/src/arrow/util/bitmap_ops.cc#L376-L379 with `left_offset == right_offset == out_offset == 1`. Then the byte-wise bit op overrides bit zero. I think the aligned bit op should only be performed when `left_offset == right_offset == out_offset == 0` (instead of only requiring they are congruent modulo 8). @pitrou what do you think? -- This is an automated message from the Apache Git Service.
