--- Comment #11 from Tamar Christina <tnfchris at gcc dot gnu.org> ---
reduced to

---
struct h {
  int b;
  int f;
} k;

void n(int m) {
  struct h a = k;
  for (int o = m; o; ++o) {
    if (a.f)
      __builtin_unreachable();
    if (o > 1)
      __builtin_unreachable();
    *(&k.b + o) = 1;
  }
}

which fails on aarch64 too
