Fallback to copy constructor not working?

I thought that when I delete the move constructor in B then the following code will still compile fine since it should still take the copy constructor to construct B objects. Why does the compiler now complain. Without the =delete it did not and called the copy constructor anyway since it was not allowed to provide a default move constructor!)

class B{
    public:
    B(){}
    ~B(){}
    B & operator=(const B & b){
        std::cout << " cannot move -> copy " << std::endl; 
        return *this;
    }
    B(const B & v){
        std::cout << " cannot move -> copy " << std::endl;        
    }

    // B(B && b) = delete; // uncomment this!
};


int main()
{
    B b( B{} ); 
}

Compiler Output with clang 3.6 (Live code)
