[plt-scheme] "variable not provided from module"

Alright, I can now compile my code. While doing do, I appear to have
uncovered a compiler bug. Since the bug report page seems to be down at
the moment, I will post it here.

I've reduced the offending code down to the following four lines:

  (module frp mzscheme
    (let-values ([(a b) (values 1 2)])
      (define (foo c) (printf "yey~n"))
      (foo 5)))

The bug occur both with 206p1 and with the exp-tagged cvs version.

        gmarceau at catacomb gmarceau $ cd ~/src/plt/collects/frtime/
        gmarceau at catacomb frtime $ rm -rf compiled/
        gmarceau at catacomb frtime $ cat frp.ss
        (module frp mzscheme
          (let-values ([(a b) (values 1 2)])
            (define (foo c) (printf "yey~n"))
            (foo 5)))
        gmarceau at catacomb frtime $ mzscheme -u frp.ss
        yey
        gmarceau at catacomb frtime $ setup-plt -l frtime
        setup-plt: Setup version is 206p1
