The point I meant to make but failed is: a pure virtual method can *only*
*ever* be called explicitly. It can't be called through the vtable because
there can be no objects of the type of this pure class, only of derived
classes, and in the vtables of this derived class the slot for this
virtual function is filled by another function (because the derived class,
to be instantiated, must have overwritten the pure function).
So, yes, I'm not surprised that the object file you produce from your
testcase doesn't contain pvMethod. But that's not a problem because in it
nobody ever calls this function. What I want to see is a testcase in which
this function *should* be there because it is, somehow, called or
otherwise required.
Does this make sense?
