Following C++11 code crashes the VC compiler, but successfully compiled by GCC.

(the code is not correct semantically, because scope of temporary objects is not defined for "FOR IN" statement)

Visual Studio 11 Beta

#include <vector>
using namespace std;

struct A {

    const vector<int>& a() { return v; }
