[GitHub] [arrow-rs] jhorstmann commented on issue #502: sliced null buffers lead to incorrect result in take kernel (and probably on other places)

   I think the problem is this [clone of the null buffer in `take_indices_nulls`]][1]  where it should instead take a slice:

    The other combinations of nullable/nonnull indices/values look ok which probably explains why this wasn't found earlier.
