I think you'd have to wrap the 1 in a UL(), ex: #define VA_START (UL(0xffffffffffffffff) - (UL(1) << VA_BITS) + 1) Otherwise IIUC a integral literal (`1`) is treated as an int, which on arm64 is LP64 making it 32b, where most configs set VA_BITS to larger than 32b. Shifting by more than the width is undefined behavior. And without it, I get compile errors. I'll send v2 with your suggestion, thanks. -- Thanks, ~Nick Desaulniers
