------- Comment #3 from pinskia at gcc dot gnu dot org  2006-04-16 23:13 -------
Confirmed, reduced testcase:
template <class T, class U>
struct Conversion
{
    static T a;
    enum { exists = sizeof((U)(a)) };
};
template<class T,class U>
struct SuperSubclassStrict
{
    enum { value = (Conversion<U*, T*>::exists)};
};
struct IObject
{
    virtual unsigned long A(void) = 0;
};
struct IFoo : IObject{};
struct IBar : IObject {};
struct Component : IFoo, IBar
{
};
struct Event : Component
{
  static const int t = SuperSubclassStrict<IBar, Event>::value;
};
