------- Comment #8 from benjamin at smedbergs dot us 2006-08-11 10:19 ------- The documentation is incorrect. RTTI is not required to find the most-derived class pointer, because the vtable contains this information natively and does not need to know anything about the type. I'm making my point from years of working software, not some theoretical discussion.
