We face related problem; classinfo mutability. my post is article_id=90722. I have noticed that classinfo relates core of D's class system. http://www.digitalmars.com/d/2.0/phobos/object.html A pointer to this appears as the first entry in the class's vtbl[]. It seems that this problem must be treated carefully.
