Well, because it gets never positive values it will never be deallocated so I think it shouldn't really crash. But yes, in any case, I fully agree that we shouldn't rely on such a weird behavior. But rather than just skipping init I don't think we should initialize OMPT either. What about chaging:

`if (RefCount == 1) `

to

`if (RefCount == 1 && !OffloadPolicy::isOffloadDisabled())`

?
