[racket] Liveliness of variables and GC

Dear all,

I am struggling to find the origin of a memory leak in a small program I
In order to help me searching, I would like to know a few details on the
implementation of Racket.

(define (f x y)
    (lambda () x))
(define g (f 2 veryBigObject) )

Can I be sure that g does not retain a pointer to veryBigObject?

2) (g is a function)

(define (f)
   (let ([x veryBigObject])

Can I be sure that veryBigObject is not retained by f during the execution
of g?

3) Same program.
g now captures its continuation. Can I be sure that this continuation does
not retain veryBigObject?

Best regards,
