It is not "one of several possible interpretation", it is what actually
happens in C++! For implementations which use vtables, the compiler
generates code to change the vtable pointer of the object as it runs
through its chains of destructors. (Presumably the compiler may detect
cases where it doesn't need to do this, but this is what happens in
principle.)
