1278        is an error action.  In that case, don't check for expected

1281        this state is a consistent state with a default action.  Thus,
1282        detecting the absence of a lookahead is sufficient to determine
1283        that there is no unexpected or expected token to report.  In that
1284        case, just report a simple "syntax error".
1285      - Don't assume there isn't a lookahead just because this state is a
1286        consistent state with a default action.  There might have been a
1287        previous inconsistent state, consistent state with a non-default
1288        action, or user semantic action that manipulated yychar.
1289      - Of course, the expected token list depends on states to have
1290        correct lookahead information, and it depends on the parser not
1291        to perform extra reductions after fetching a lookahead from the
1292        scanner and before detecting a syntax error.  Thus, state merging
1293        (from LALR or IELR) and default reductions corrupt the expected
1294        token list.  However, the list is correct for canonical LR with
1295        one exception: it will still contain any token that will not be
