This causes the compiler to complain about casting a pointer to an integer of a different (smaller) size. To avoid this, cast to an integer of matching size first, then perform an int->int cast to perform the size change. This signals explicitly that we do want to change the size, and avoids the compiler warning. This is legitimate since we know the pointer actually stores a small integer, not a pointer value.
