--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The gimplifier is handed call to foo with argument of type Derived, the
conversion has been omitted.  As the call expects a type (in this case empty
class) passed by value, but the argument is one that should be passed by
invisible reference, this obviously crashes during expansion.
