[Bug c++/37911] New: Operator= called on a non constructed object.

[wonsjb at gmail dot com]

If I compile this code:
(g++ -o element element.cpp)

#include 
#include 

using namespace std;


class element
{
public:
element()
{
cout << "element() = " << this << endl;
}
element(const element &e)
{
cout << "element(const element &e="<< &e << ") = " << this << endl;
}
~element()
{
cout << "~element() = " << this << endl;
}
element &operator=(const element &e)
{
cout << "operator=(const element &e="<< &e << ") = " << this << endl;
}
string getString() {return a;}
private:
string a;
};

element parse()
{
element aelement;
return aelement;
}

element parse2()
{
element aelement;
return aelement;
}

bool toto=true;

int main()
{
element el = toto ? el = parse() : parse2();
return 0;
}



It compiles without warning or error.

However, the result is:
element() = 0xfeffc680
operator=(const element &e=0xfeffc680) = 0xfeffc67c
element(const element &e=0x8049ea8) = 0xfeffc67c
~element() = 0xfeffc680
~element() = 0xfeffc67c


You can see that operator= is called on a object of address 0xfeffc67c before
this object is constructed.

I am not sure what should be the right behavior here.
Maybe a compile error.
