------------------------------------------------

Forgive me if this topic has been brought up before, but I was curious
as to why I was getting this behavior and was hoping someone
knowledgeable could explain. :)

I "feel" like even without the explicit call to a simple base ctor(),
mangling should still happen correctly. This doesnt, however, seem to be
the case...

Of note: simply doing a 'pass' in BadSubClass seems to be sufficient as
well; so, it has something to do with defining a ctor() in the child and
not explicitly invoking the parent's ctor.
