Okay, so yes it is good to note that the GNU lexical generator toolkit does not generate unicode parsers and isn't re-entrant.
In general, parsing the same text from multiple threads seems like it could probably lead to more problems than just the fact that the parser generator toolkit for compiler writers isn't re-entrant, but that sounds more like a problem for the 'design' of these folk's client's codebases than anything else to me.
It would be nice to see a simple LL(1) lexer/parser generator in C that handles unicode and re-entrancy, although again, the latter one seems like something of a complex concept to me. Having the library generate parsers which are stable across multiple threads using generated parsers to parse different things at once seems like the only stable notion that I'd care about, so I will assume that is what this fellow is talking about.
