Yes. They changed functions to take 64-bit integers instead of 32-bit ones.
When called by code compiled against a previous version, the upper half will
be garbage. On some architectures (depending on how exactly arguments are
passed, but they will usually be big-endian ones), even the whole thing.
(There, the lower half will be complete garbage, and the upper half will be
what should be the lower half. Or in the worst case, some architectures
might even decide to switch from register to stack passing, making the whole
number or even also the other arguments complete garbage.)
