[Bug c++/39463] New: The type a std::vector cannot work with classes with the protected copy-constructors

["lisp2d at lisp2d dot net" <gcc-bugzilla at gcc dot gnu dot org>]

The type a std::vector cannot work with classes with the protected
copy-constructors.

class A{
public:
 explicit A(const A&){};
};
std::vector<A> v;
A a;
v.push_back(a); // an error

Copy protection deleting solves a question.

class B{
public:
 B(const B&){};
};
std::vector<B> w;
B b;
w.push_back(b); // good

What is the matter?
