That's not a "real" Voldemort type with a closure; try this instead:

auto foo(){
    int x;
    struct S {
        int baz() { return x; }
    }
    return S();
}
void bar(){ typeof(foo()) a; } // Error: cannot access frame pointer of
xx.foo.S

This could either be an oversight (= bug), or it could be intentional. I
suspect the latter, because it allows to actually declare a Voldemort variable
that is only initialized later.
