... because the clang sanitizers generally work better than the gcc sanitizers (in my experience). If someday people stop using the clang sanitizers and everyone uses the gcc sanitizers, or if the clang people change their counted_by implementation to be gcc compatible, we could revert the swapping of the fields. But for now, this appears to be unlikely. Bruno
