--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.
A does not need to have a ctor either.
This is also invalid:
```
struct A{ int t; };

template<typename T>
struct B{
    B(A &a) : a(a){}

    A &a{ 4 }; // this is wrong
};

int main(){
    A a{5};

    B<double> b(a);
}
```

GCC has incorrectly accepted this since NSDMI support was added in 4.7.
