--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Another testcase:
```
static int t =3D 0;
_Complex float f()
{
        t++;
        return 0;
}
int main() {
        t =3D 0;
        f() * 1j; // incorrectly invokes f() twice
        if (t !=3D 1)
          __builtin_abort();
}
```=
