Many thanks!  This certainly seems to fix the problem.  The build
finishes cleanly now with no sign of stack overflow errors.

% cat e.ss
(define seq:e (lambda (n) (if (= (modulo n 3) 2) (- n (quotient n 3)) 1)))

(define continued-fraction
  (lambda (n d k)
    (let lp ((k k)
             (accum (d k)))
      (if (= k 1)
          (/ (n 1) accum)
          (lp (- k 1) (+ (d (- k 1)) (/ (n k) accum)))))))

(time (+ 2 (continued-fraction (lambda (n) 1) seq:e 1000000)))

% csi < e.ss ; csc e.ss ; ./e
; This is the CHICKEN interpreter.
