I'd bet it is a consequence of the introduction of `letrec*'. The

If you use `letrec' in your code, check if it is ok.
I've just been checking for that one.
At least the petrofsky extraction and Kiseljov's keyword syntax macros
do not use letrec directly.
I'm afraid it's something within the macro expander itself... which
means that it might effect more code than just the one here.
