--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
This is expected. Use -fno-trapping-math as this loop is no longer vectorized:\
```
        for (int i = 0; i < LEN_1D; i++) {
            if (d[i] < (real_t)0.) {
                exit (0);
            }
            a[i] += b[i] * c[i];
        }
```

Due to having trapping expression after the early break.
