--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
for write_run_char_ptr_ref we get:

  <bb 5> [local count: 955630225]:
  # n_18 = PHI <n_8(5), n_15(4)>
  _2 = *p_10(D);
  _3 = _2 + 1;
  *p_10(D) = _3;
  *_2 = _13;
  n_8 = n_18 + -1;
  if (n_8 != -1(OVF))
    goto <bb 5>; [89.00%]
  else
    goto <bb 3>; [11.00%]

So I think this is still correct based on aliasing rules ...
That is the what char* points to can be writing to a reference/pointer type of
(char*&).

Now we could version this loop for aliasing but I don't know how much it would
benifit in general.
