--- Comment #5 from Matthias Klose <doko at gcc dot gnu.org> ---
reduced test case for filters.i:

double a, b, d, e;
c, f, g;
double fn1() {
  double t;
  if (t < 0.0)
    t = -t;
  if (t < 1.0)
    return 1.0 - t;
  t = -t;
  if (t < .5)
    return t * t;
}

double fn2(double p1) {
  if (p1 < 1)
    b = p1 * p1 / 3.0;
  if (p1)
    return 6.0 * p1 * p1;
}

double fn3(double p1) {
  if (c == 0)
    fn4();
  else if (c == 2)
    return fn1();
  else if (c == 5)
    return fn2(p1);
  else if (c == 3) {
    d = p1 * p1;
    return d;
  }
}

fn5() {
  double h, j;
  int k = f, i;
  h = a;
  i = 0;
  for (; i < k; i++) {
    g = 0;
    for (; g < k;) {
      e = ((i + 1.0) / k - 1.0) * h;
      j = (2.0 * g - 1.0) * fn3(e) * fn3(j);
    }
  }
}
