--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Reduced testcase for -fopenmp:
struct J;
extern "C" int setjmp (struct J[1]) throw ();
extern struct J j[1];
void foo (unsigned long);

void
bar (void)
{
  if (setjmp (j) == 0)
    {
#pragma omp parallel
      for (long int k = 0; k < 10; ++k)
        foo (k);
    }
}

Started likely with r198096.
