[Bug c++/39045] New: Not inited referense.

[alexey dot veselovsky at gmail dot com]

g++ allows to exist not inited reference in this case:

struct X
{
   int &x;
};

int main()
{
X* p_x = new X; // now there is not inited reference (p_x->x)
// now we can try to use p_x->x
std::cout << p_x->x << std::endl; // segmentation fault
return 0;
}

There are no errors or warnings. Compilation is successfull. 

I have tested on g++ (GCC) 4.2.4 (Ubuntu 4.2.4-1ubuntu3).
Also it "works" on g++ 4.3.

I think it should be error, not warning. (comeau and ms vc claims it as error)
