Re: new ICE #122 (20000814): member function of class template

[Marco Franzen <Marco dot Franzen at Thyron dot com>]

The same ICE 122 can be triggered even without using templates.
(Not sure whether this is correct C++, 
but in neither case should the compiler crash.)
=========================================
class Base {
protected:
  operator bool() { return true; }
};

class Derived: Base {
  Derived (): Base () { if (Base); } // <- here
};
==========================================
The intention of this code is to call the conversion operator of the Base
subobject.
