C/C++ :: Class Square Composed Of Two Points - Destructor Called Twice

I have a class Square that is composed of two Points, I pass the former to the Square as references (second ctor) and two Points are created.

The problem is, at the end of the program, 4 Points are now being deleted which suggests that somewhere copies were made (regardless of the references) and the m_p1, m_p2 have different addresses than p1 and p2.

#include <iostream>
using namespace std;
class Point {
public:
Point();
Point(double x,double y);
double printCor() const;

[Code] .....

Even though, the objects were passed to the ctor by references, the copy constructor (compiler generated) for Point was called and now we have two points and an object square with distinct Point objects.
