/* PR middle-end/33880 */
/* { dg-do compile } */
/* { dg-options "-O2 -fopenmp" } */

int
foo (void)
{
  int i = 0;
  void bar (void) { i++; }
  bar ();
  #pragma omp parallel for
    for (i = 0; i < 10; i++)
      ;
  i = 3;
  bar ();
  return i;
}

ICEs the same way.

Jakub, is there any chance that it can still get fixed for 4.3.0?
