--- Comment #1 from Martin Liška <marxin at gcc dot gnu.org> ---
It's again the same story. As I've already explained you multiple times,
compiler optimizes a dead code even without any optimization level. Thus we end
up with:

f (int i)
{
  int res;
  int D.1916;
  int _3;

  <bb 2> :
  res_2 = i_1(D) * 2;

  <bb 3> :
  _3 = res_2;

  <bb 4> :
<L3>:
  return _3;

}

Please do not create such bugs.
