I do got stack overflow thus need several compile opts to fix it. Not sure if it is what you mean by "You get overflow using 32-bit types here."
No, what he meant was that your n does not always fit into a 32-bit integer, so the integer will overflow (i.e. once it exceeds its maximum value it will wrap around and become negative).
