--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Reduced further:
```
typedef decltype(sizeof(0)) size_t;
struct ts1 {
  int spans[6][2];
};
struct gg {
  int t[6];
};
ts1 f(size_t t, struct ts1 *s1, struct gg *s2) {
  ts1 ret;
  for (size_t i = 0; i != t; i++) {
    if (!(i < t)) __builtin_abort();
    ret.spans[i][0] = s1->spans[i][0] + s2->t[i];
    ret.spans[i][1] = s1->spans[i][1] + s2->t[i];
  }
  return ret;
}
```
