Construct object with itself as reference?

Question

I just realised that this program compiles and runs (gcc version 4.4.5 / Ubuntu):

#include 
using namespace std;

class Test
{
public:
  // copyc         


        

Answer 1

I don't know the spec reference, but I do know that accessing an uninitialized pointer always results in undefined behaviour.

When I compile your code in Visual C++ I get:

test.cpp(20): warning C4700: uninitialized local variable 'b' used
