If the size of `size_t` and `ulong` are not the same this doesn't
really fix the issue, just silence the compiler warning. If ulong
is smaller than size_t on some platform we will read data outside
the variable address when de-referencing.

Might be more correct to assign size to a variable of the correct
size first, then pass a pointer to that.
