Did you read the changes page for 3.4.x?

Your code is invalid C++.
Do the following instead:
template<class T>
class DerivedClassThatDoesNotWork : public MiddleClass<T>
{
 public:
  DerivedClassThatDoesNotWork(int x, T y) : MiddleClass<T>(x, y)
    {
      this->V = 5;
	  /* or this: */
	  MiddleClass<T>::V = 5;
    }
};


Thanks,
