this localizes the conversion to int in the function; the parameter was
previously changed in:
6ab496ed fix some 'unsigned integer overflow' warnings in ubsan

implicit conversion from type 'uint32_t' (aka 'unsigned int') of value
2350919223 (32-bit, unsigned) to type 'int' changed the value to
-1944048073 (32-bit, signed)
