Would using `long long` instead of `long` be a potential fix then? I'm not a

I think it is better to use uint32_t and uint64_t and-or
int32_t and int64_t so that you get the exact same integer
length no matter the kernel and libraries.
In this case, some tricky logic was used so that rollovers
of the 24-bit signed hardware counters
were properly handled by carry/borrow to the next byte of
the signed 32-bit integer, which was then
converted to float. Some of the trickiness is due to the
24-bit hardware being zeroed during home
and spindle index operations, you have to make sure the
sign-extended bits are also zeroed.
