Note, that the test mentions:

FIXME: The 'short' type gets overflown with sporadic values on CUDA.

so there might be some non-deterministic issues going on.

Additional, I remember looking into it and submitting a bug with hhd specifier (https://forums.developer.nvidia.com/t/incorrect-results-for-printf-with-hhd-format-specifier/218643) but that seems to be resolved now.
