Internal compiler error

[Mark Crosland]

I have seen several examples of deriving a class from a base class 
that is a template class, and passing the derived class as the
template argument of the base class (Coplien, Barton/Nackman).

class B : public A <B> {
    .
    .
    .
};

Of course the examples are 5+ years old. Are those examples no longer
valid? Or am I missing something :)

Thanks,
Mark
