Description:   Last confirmed: 2008-01-25 10:04 Opened: 2007-10-24 12:21 
This is with both 4.2 and 4.3 on x86_64/Linux.

gfortran-4.3 -fopenmp a.f90
a.f90: In function 'MAIN__':
a.f90:3: internal compiler error: in extract_omp_for_data, at omp-low.c:162

Test case (by Xavier Andrade):
--------------------------
program testbug
  integer :: ii
  !$omp parallel do
  do ii = 1, 1000
  end do
contains
  subroutine something()
    ii = 0
  end subroutine something
end program testbug
--------------------------

/* 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.

------- Comment #2 From Andrew Pinski 2007-11-19 05:37 ------- 
Confirmed.  Another nested function with openmp interaction case.

------- Comment #3 From burnus@gcc.gnu.org 2008-01-13 21:54 ------- 
Jakub, is there any chance that it can still get fixed for 4.3.0?

------- Comment #4 From Jakub Jelinek 2008-01-25 10:04 ------- 
Yes.  Have a fix, now need to write some more testcases.
