It will depend on when pointer to vtable is initialised.
generally if constructor is already defined compiler insert
code to initialise virtual table pointer as first statement
inside defined constructor. If vptr is initialised before
calling virtual function then it will be invoked, if vptr is
not initialised then it can crash.
