Well, first of all, in order for a virtual function to "function" (ha)
correctly, both the base class and the derived class must have it
defined as a virtual function......

class a
{
virtual assign(int x);
};
class b :  public a
{
virtual assign(int x);
};

the above will "work".....although I have found some problems with
borlands implementation of C++......but they won't effect most people...

Assuming that you meant to say both of those functions were virtual,
then I would begin to suspect a stack / heap problem -- that is (once
again), if you indeed meant to declare both of those as virtual AND it
works in a "small" program and crashes in a larger program.....

'course simple memory corruption would do the same thing too......
