--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
here is a better testcase which does not use vfork which is implicit
returns_twice:
```
typedef short __attribute__ ((__vector_size__ (64))) V;
V v, w;
void g(void) __attribute__((returns_twice));
V foo (V a, V b)
{
g();
b &= v < b;
return (V){foo (b, w)[3], (V){}[3]};
}
```
