I thought of that too, but they are called from the Run method after the
object is constructed (and before it is deleted). Calling the methods
directly from main before the call to Run works, so the object is
properly initialized.
Knowing that this only happens with gcc2, I think it somehow misses the fact
that the method is virtual when compiling the base class, and generates a
direct call instead of a virtual one (going through the vtable). I'll
see if I can write the code in a different way to work around the
problem, then.
