Sorry, I don't understand that. The problem is that liboffload might be returning an `int32_t` via `void *pOut` yet the consumer might be mistakenly thinking that it's a `float`. The sizes would match and there is no way (currently) to detect such mismatch. After this patch the consumer would be able to verify (i.e., `static_assert`) what type do those bytes in `pOut` actually represent.
