--- Comment #8 from Peter Bergner <bergner at gcc dot gnu.org> 2012-11-07 23:39:56 UTC ---
...and the reduced test case I used for the above.  Does any of the above make
sense for anyone?


class CObject {};
class CMsgProc:virtual public CObject { };
template < typename ValueType > class CTypesafeValue { };
class CRemapPidIndex:public CTypesafeValue < short unsigned int > {};
class ICarousel
{
    virtual ~ ICarousel ();
};
class IPlayout
{
    virtual ICarousel * CreateCarousel (CRemapPidIndex PidIndex) = 0;
};
class CCarousel:public CMsgProc, public ICarousel { };
class CPlayout: public IPlayout 
{
    CCarousel *CreateCarousel (CRemapPidIndex PidIndex);
};
CCarousel *CPlayout::CreateCarousel (CRemapPidIndex PidIndex) { }
