This is clearly a bug, and a regression on 3.3/mainline w.r.t. 3.2.x. 
 
Here's an extract: 
------------------------- 
template <class T> struct B { 
  virtual operator T() const = 0; 
}; 
 
template <class T> 
struct D : B<T> { 
  virtual operator T() const; 
}; 
 
typedef int i; 
typedef B<i> Bi; 
 
D<int> i32; 
--------------------------- 
 
g/x> /home/bangerth/bin/gcc-3.2.3/bin/c++ -c x.cc 
g/x> /home/bangerth/bin/gcc-3.3.3-pre/bin/c++ -c x.cc 
x.cc:13: error: cannot declare variable `i32' to be of type `D<int>' 
x.cc:13: error:   because the following virtual functions are abstract: 
x.cc:2: error:  B<T>::operator T() const [with T = i] 
 
W.
