[Bug c++/13005] [3.3/3.4 Regresssion] [aliasing] Pointer wrongly adjusted for derived class containing virtual function

AFAICT the report so far is that Base is not at offset zero within
Derived. That is not a bug. The original test case contains this

    Base() : before((Derived*)this), after((Derived*)this) {}
 
which is unspecified. At that point Derived is incomplete.
So it is unspecified as to whether the old-style cast is treated as
a static_cast or a reinterpret_cast.  See [5.4]/6
