bug with call-with/cc and lambda?

I've  been playing  with a  few Scheme  interpreters and  I noticed  the
following issue in Guile.

When I do

    (define (f x) (call-with-current-continuation f))
    (call-with-current-continuation f)

I get the  expexted behaviour: Guile just hangs (starts to  use a lot of
processor power).

However, when I do the  following very similar construction, Guile hangs
but also  starts to  consume a lot  of memory, giving  me the  idea that
something that could be tail-recursive somewhere isn't:

    (define (f x) (call-with-current-continuation (lambda (x) (f x))))
    (call-with-current-continuation f)

Shouldn't this use constant memory?

Thanks. :)
