and that is the code for it:


                if (IsOperator(complete)) {
                    nodes[complete].p.parent = incomplete;
--> 1127            incompletePtr->constant = incompletePtr->constant
                            && nodes[complete].constant;
                } else {
                    incompletePtr->constant = incompletePtr->constant
                            && (complete == OT_LITERAL);
                }
