--- Comment #8 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Won't that break with function-local statics?  Those can certainly refer to
other function-local static, with this patch gcc might think the other ones are
unused.  I mean something like:

int **
foo (void)
{
  static int a = 0;
  static int *b = &a;
  static int **c = &b;
  return c;
}
