The Lifetime of a Bound Temporary Object

You can safely bind a reference to a temporary object. The temporary object to which you bind the reference persists for the lifetime of the reference.
 
class C {
  int j;
public:
  C(int i) : j(i) {}
};

void main() 
{
  const C& cr = C(5);//bind a reference to a temp; temp's destruction deferred to the end of the program
  C c2 = cr; //use the bound reference safely
}//temporary destroyed here along with its bound reference
