Why an extra vfptr is added/required in case of virtual inheritance?

How i fix it?

You can, however, declare a pointer to a native type and control its lifetime in the constructor
and destructor and finalizer of your managed class (see <mshelp:link tabindex="0" keywords="0d09d3f1-13a0-4041-8178-402aad667edd">Destructors and Finalizers in Visual C++
for more information)."
