State-Changed-Why:
This is not a bug:

  3.10  Lvalues and rvalues                                 [basic.lval]

6 An  expression which holds a temporary object resulting from a cast to
  a nonreference type is an rvalue (this includes the explicit  creation
  of an object using functional notation (_expr.type.conv_)).
