Thread: Classes, pointer to itself to access from a child class

Is it possible to compile under g++?
I've tryied compiling this with no success

Code:

#include <iostream> 
using namespace std;

class SmallComponent {
private:
    BigThing *outer;
public:
    void sumar() {
	int x = outer->i+outer->j;
	cout << x << endl;
    }
    SmallComponent(BigThing *outer) : outer(outer) {}
};

class BigThing {
private:
    SmallComponent small;
public:
    doSomething() {
	small.sumar();
    }
    int i;
    int j;
    BigThing() : small(this), i(2), j(4) {}
};


int main() {
	BigThing clase;
	clase.doSomething();
	return 0;
}

It returns:
