Problems of this kind arise when the vtable of the derived class is not linked 
to the binary. g++ put the vtable in the object file where the first 
non abstract virtual method of the object is defined. This behavior also gives 
problems if the first virtual function is inline. In this second case the 
compiler yields the vtable in ervery object file where the class header is 
included.
