Details:

On page 106 of Dyvbig's 3rd edition TSPL

(also online at http://www.scheme.com/tspl3/control.html#./control:h5),

this example:



(let ((x 'a))

  (let ((f (lambda () x)))

    (cons (call/cc

            (lambda (k)

              (fluid-let ((x 'b))

                (k (f)))))

          (f))))



should return (b . a), but Kawa returns (a . a).
