--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
uint64_t is `unsigned long` while __u64 is `unsigned long long`; these 2 types
don't alias in the access sense.
So that looks like an aliasing issue.
What options are you compiling with?
If at -O2 (or -Os or -O3), then you either need -fno-strict-aliasing or you
should fix the code to use either memcpy, an union or change to use the same
64bit integer type.
