--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Reduced testcase:

struct A {};
struct B { virtual A foo () const; };
struct C { A foo () const; };
struct D : virtual B { A foo () const {} };
struct F : D { virtual int bar () const; };
int F::bar () const { return 0; }
A C::foo () const { return A (); }
