[gameprogrammer] Re: Pure virtual function getting called

Hi Kevin,

I seen to remember running into this problem at one point and
 believe its "undefined behaviour" according to the standard,
i.e. compiler-dependent. Could be wrong though :)

A simple alternative might be to store the class name in the
base class and pass in its value via the constructor. Get's
you past calling a virtual function at the cost of allocating
a string for every class instance.
