OK, that makes sense, 64-bit target is an essential piece of this as part of
the problem is that the loop index variable i is not chosen as an induction
variable because it is not DImode. If you change the code to make size, i, and
n all 64-bit, then i is chosen as one of the IVs and this infinite loop problem
does not occur.
