The native range-based for version, however, compiles fine with gcc 4.6 (which is the only version to support it):

#include

template<typename> void f() { int A[6]; for(auto&& x : A) ; }

Why does this compile? I don't see how any rvalue can be available in that context.

Wouldn't auto deduction make x an lvalue reference here? Sebastian
