Comment (by sjamaan):

 It looks like the whole call-cc stuff is just a red herring. The following
 simplified version fails in the same way

 {{{
 #!scm
 (define (add x y)
   (if (zero? y)
       x
       (add (add1 x) (sub1 y))))

 (define (fib x)
   (if (or (= x 0) (= x 1))
       x
       (add (fib (sub1 x))
            (fib (sub1 (sub1 x))))))

 (print (fib 30))
 }}}
