I see.  But I still don't know what is wrong with this.
Could you try with simpler examples?  What happens with
the followings, for example:

(define (foo)
  (let ((x #f))
    (begin (set! x (bar))
           (or x x))))

(define (foo)
  (let ((x #f))
    (begin (bar)
           (or x x))))

(define (foo)
  (let ((x #f))
    (set! x (bar))))
