I just verified, the sample code at that link doesn't even compile on
modern gcc for the same reason I described:
=====
x.cc: In static member function `static MyAbstractClass
MyWrapperClass::getClass()':
x.cc:35: error: invalid return type for function `static
MyAbstractClass MyWrapperClass::getClass()'
x.cc:35: error: since type `MyAbstractClass' has abstract virtual functions
x.cc:37: error: cannot allocate an object of type `MyAbstractClass'
x.cc:37: error: since type `MyAbstractClass' has abstract virtual functions
=====
The method above must be changed to do
MyAbstractClass& MyWrapperClass::getClass()
in order for it even to build at all. There's some kind of crack
smoking going on there.
