957 detecting the absence of a lookahead is sufficient to determine
958 that there is no unexpected or expected token to report. In that

960 - Don't assume there isn't a lookahead just because this state is a
961 consistent state with a default action. There might have been a
962 previous inconsistent state, consistent state with a non-default
963 action, or user semantic action that manipulated yychar.
964 - Of course, the expected token list depends on states to have
965 correct lookahead information, and it depends on the parser not
966 to perform extra reductions after fetching a lookahead from the
967 scanner and before detecting a syntax error. Thus, state merging
968 (from LALR or IELR) and default reductions corrupt the expected
