<pre>Consider the following code:
#include <memory>
struct S {
private:
S();
public:
void f() { (void)std::make_shared<S>(); }
};
struct T {
protected:
T();
public:
void f() { (void)std::make_shared<T>(); }
};
S::f() will fail to compile because S::S() is private, but T::f() does not fail
to compile with a protected constructor. Giving the class a data member, or
marking the class as final, will cause T::f() to fail as well. Likely caused by
use of EBO.</pre>
