Looking at the whole function, is uintptr_t really the right type to use
here? ctr does not seem to contain the value of a pointer variable, so
this looks wrong to me...
Do you get a compiler warning here? If so, how does it look like?
Anyway, I think it would be better to use a uint64_t or uint32_t type
here instead if possible?
