[Bug libgomp/35625] New: schedule(guided) loops forever if ((end - start) % incr) != 0

["jakub at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

int
main (void)
{
#pragma omp parallel
  {
    #pragma omp for schedule (guided, 10)
      for (int i = 0; i < 1826; i += 10)
        ;
    #pragma omp for schedule (guided, 10)
      for (int i = 0; i > -1826; i -= 10)
        ;
  }
  return 0;
}
hangs - after going through all iterations keeps calling GOMP_*_next forever,
each time returning true and assigning an empty range.
