--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed. Since r7-6606-g0b90c54148e937.

This is obvious an use of dump_file without checking it is nullptr:
  if (skip_count > e->count ())
    {
      fprintf (dump_file, "  Capping count; expect profile inconsistency\n");
      skip_count = e->count ();
    }
