The compiler (__DMC__ == 0x84x) is not able to handle the following program:

template < typename T > class A
{
public:
    virtual T get() const           { return T(5); }
};

template < typename T > class B : public A< T >
{
public:
    virtual T get() const           { return T(6); }
};

void foo()
{
    A< int >* a= new A< int >;
    B< int >* b= dynamic_cast< B< int >* >(a);      // <<-- Error
}
