[Bug c++/21601] New: Friend of template argument constructor

["charles dot gretton at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

If we try and make \class{A} inherit from \class{B<A>} which is
friends with A's constructor, the compiler segfaults.

template<typename T>
class B
{
public:
    friend T::T(B&);

//     void some()
//     {
//         T t = T::T(*this);
//     }
    
};

class A : public B<A>
{
public:
    A(B<A>& b);
};


A::A(B<A>& b)
    :B<A>(b)
{
}
