Subject: about prvate field (maybe it's a bug for g++ 4.1.2)

Hi,



the value of private field is changed by operator &.

attached are source files.

/******************/
// Temp.h
/******************/

#include <string>
using std::string;
class Temp{
        private:
        string source;
        public:
                Temp();
                Temp(string str);
                string getSource()const;
};

/******************/
// Temp.cpp
/******************/

#include <string>
#include "Temp.h"
using std::string;
Temp::Temp(){};
Temp::Temp(string str){
        source = str;
}
string Temp::getSource()const{
        return source;
}

/******************/
// TempMain.cpp
/******************/
#include <string>
#include <iostream>
#include "Temp.h"
using namespace std;
int main(){
        Temp temp("1111111111111111");
        cout<<"BEGIN source = "<<temp.getSource()<<endl;
        string* strp = &(temp.getSource());
        *strp = "22222222222";
        
        cout<<"EDN source = " <<temp.getSource()<<endl;
}



////////////////////
// out 
////////////////////

BEGIN source = 1111111111111111
EDN source = 22222222222
