That is unfortunately untrue.
The C++ standards committee don't even say anything thing about the
layout of a non-POD class.
There is a C++ ABI defined the Itanium platform

by some C++ compilers vendors -- not the C++ standards committee --
but it is not part of standard C++ definition.

That is untrue. Take for example g++ from GCC-2.95.x and GCC-3.x
series.
