Looks like a bug in smie.el, which should disappear when you grow your
grammar.  You can remove the (cl-assert (numberp (car cons))) in smie.el
to work around the problem, or more simply add some dummy thing in `id',
such as:

(defconst rnc-mode-smie-grammar
  (smie-prec2->grammar
   (smie-bnf->prec2
    '((id ("(" id ")"))
      (pattern ("element" id)
               ("empty"))))))
