Version 2.2.2 of g++ gets the message:

> cp-decl.c:6536: failed assertion `0'
> gcc: Internal compiler error: program cc1plus got fatal signal 6

when trying to compile the following 20-line file:

//** -- Cut here ----------------- ***/
class block;
class integer;

class block {
public:
  block() {}
  virtual integer operator + (block& a) = 0;
  virtual integer operator + (integer& a) = 0;
};

class integer : public block {
  int i;
public:
  integer(int x) : i(x) {}
  virtual integer operator + (block& a);
  virtual integer operator + (integer& a);
};

block& x(integer(5));
integer& y(x);
//** -- Cut! -------------------- ***/

Thanks for your attention, and thanks for GNU!
