syntax and undefined variable

[Damien Mattei <damien.mattei@gmail.com>]

hello,

when i try to simplify my code that works it no more works, if change
#'list by list it fails with this strange error:
ice-9/boot-9.scm:1685:16: In procedure raise-exception:
In procedure variable-ref: Unbound variable: #<variable 76e5ef9478f0 value:
#<undefined>>

the code is:

(define-syntax $bracket-apply$

  (lambda (stx)

    (syntax-case stx ()

      (($bracket-apply$ container arg-bracket ...) ;  . args-brackets


       (with-syntax ((parsed-args ;;#`(list
#,@(parse-square-brackets-arguments-lister-syntax #`(#,@#'args-brackets)))))

     (cons #'list ; list : cause ERROR in start-λογικι-guile+.scm
(logic-test) : ice-9/boot-9.scm:1685:16: In procedure raise-exception:
   ;; In procedure variable-ref: Unbound variable: #<variable 785f3e25c8f0
value: #<undefined>>
         (parse-square-brackets-arguments-lister-syntax #'(arg-bracket
...)))))

   (display "$bracket-apply$ : #'parsed-args=") (display #'parsed-args)
(newline)

   #'($bracket-apply$next4list-args container parsed-args))))))

the strange things is that it can ran on complex code that use this library
(bracket-apply) but fail with others one.

It is not important as i have a good working version but if someone have an
idea?
the problem is that i have no idea for debug of which value is undefined as
the back trace just output this:

scheme@(guile-user)> (logic-test)
test 1
(or (and (not a) (not b) (not c) (not d)) (and (not a) (not b) (not c) d)
(and (not a) (not b) c (not d)) (and (not a) b (not c) d) (and (not a) b c
(not d)) (and (not a) b c d) (and a (not b) (not c) (not d)) (and a (not b)
(not c) d) (and a (not b) c (not d)) (and c (not d))) =
