Flex 2.5.35: fatal flex scanner internal error--end of buffer missed

Hi:


I received this message from flex when trying to write an EOF rule
looking for unterminated curly braces. I ended up writing a rule
like:




<curly><<EOF>> {
                                                        Token t("{", "{", yyextra->oldsrc());


                                                        yyextra->token() = t;


                                                        return 1;
                                                }


This error happens only if I enable error recovery in Parse::Yapp (a
Perl clone of yacc). I would prefer if I could use error recovery to
emit more useful messages, but this has had me stumped for awhile.


Thanks,

[I see notes saying that if you longjmp out of the lexer and call it
again without resetting the input stream, this error often results.
