            Bug ID: 58551
           Summary: [4.9 Regression] ICE with abort in OpenMP SESE region
                    inside of some loop
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Keywords: ice-on-valid-code
          Severity: normal
          Priority: P3
         Component: middle-end
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jakub at gcc dot gnu.org

/* { dg-do compile } */
/* { dg-options "-O0 -fopenmp" } */

void
foo (int *a)
{
  int i;
  for (i = 0; i < 8; i++)
    #pragma omp task
    if (a[i])
      __builtin_abort ();
}

ICEs in 4.9, because __builtin_abort () bb after outlining the SESE region has
bogus loop_father.
