    void aig_exporter::collect_var_substs(substitution& subst, const app *h,
        const expr_ref_vector& vars, expr_ref_vector& eqs) {
        for (unsigned i = 0; i < h->get_num_args(); ++i) {

                if (subst.find(v, 0, othervar)) {
                    eqs.push_back(m.mk_eq(latchvar, othervar.get_expr()));
                } else {
                    subst.insert(v, 0, expr_offset(latchvar, 0));
                }
            } else {
                eqs.push_back(m.mk_eq(latchvar, arg));
            }
