rvalue to lvalue conversion Visual Studio

Question

In Visual Studio 2012RC there are some non-standard extensions. For example this code compiles:

#include 

using namespace std;

void value(str         


        

Answer 1

Basically, VS will allocate the space somewhere and just let the reference point to it, as if it was a reference-to-const without the constness (or in C++11 an rvalue reference).

You can disable this behaviour with the /Za (disable language extensions) compiler switch under

Properties -> C/C++ -> Language

If I remember correctly.
