--- Comment #5 from Daniel <Daniel.Withopf at web dot de> --- As a sidenote, the original example is also compiling if test object is made non-const, i.e. "const Derived test;" is replaced with "Derived test;" If the argument in Comment 1 is true than the program would still be ill-formed in this case, wouldn't it?
