[Bug c++/15705] New: nested class access private sourronding members

["aplanas at bic dot es" <gcc-bugzilla at gcc dot gnu dot org>]

Nested class 'Inner' can access private member 'i' of 'Outer' class, and 'Inner'
is not declared friend of 'Outer'

--- CODE ---
#include<iostream>
using namespace std;

class Outer {
private:
  int i;

public:
  void set(int ii) { i = ii; }
  void print() { cout << "[Outer] Valor de I=" << i << endl; }
  class Inner {
  public:
    void set(Outer* o, int ii) { o->i = ii; }
    void print(Outer* o) { cout << "[Outer::Inner] Valor de I=" << o->i << endl; }
  };
  //friend struct Inner; // NOTE: it is commented!
};

int main() {
  Outer o;
  o.set(10);
  o.print();

  Outer::Inner i;
  i.print(&o);
  
  return 0;
}

--- END CODE ---
