let a n =
  let x = ref 1.0 in
  for i = 1 to n do
    x := !x +. 1.0;
  done;
  !x

let b n =
  let x = ref 1.0 in
  for i = 1 to n do
    x := !x +. 1.0;
  done;
  !x +. 0.0

The code produced for a and b respectively differ greatly, even the inner 
loops. Can someone from Caml team clarify the issue?

P.S. Native code obviously.
