No I don't think we meant them to be so. And it is certainly permissible
for an implementation to use different (virtual) member functions to
implement the catch & dynamic cast machinery. So (a) the vtables
must only be emitted by the compiler building the runtime, and (b)
a user cannot derived from those classes.
