--- Comment #2 from Marek Polacek <mpolacek at gcc dot gnu.org> --- Doesn't ICE without "auto..." when the lambda's operator() is not a template. We crash on ((struct basic_string_view *) <<< Unknown tree: void_cst >>>)-><<< Unknown tree: baselink >>> which is a tree build_new_method_call gives us in a template.
