--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
```
int main()
{
        int t =3D c;
        c |=3D d / a;
    b =3D (c) >=3D ((e %=3D 0x6B1D8456) > (res ^=3D t));
    printf("%d\n", res);
}
```
gives -104
While:
```
int main()
{
        c |=3D d / a;
        int t =3D c;
    b =3D (c) >=3D ((e %=3D 0x6B1D8456) > (res ^=3D t));
    printf("%d\n", res);
}
```

Gives -112=20
Both are valid way of representing the original code as there is no sequence
point between them.

Note C++11 makes this well defined.=
