[Chicken-users] Strange memory leak with lazy-seq

[Kooda]

Hi!

I’ve been playing with lazy-seq for the past few days and found a very
strange behaviour:

The heap of the following program keeps growing rapidly in csi, running
the same program after compilation seems to slow down the growth quite a
lot but the heap isn’t constant as I was expecting it to be.

Here is a test case of the problem:


; Start this script with `csi -:D -:hi100k -:hg101` to observe heap resizing

(use lazy-seq)

(define (complex-stream seq)
  (lazy-map identity seq))

; This seems to leak:
(lazy-each void (complex-stream (lazy-numbers)))


; This doesn't:
#;(lazy-each void (lazy-map identity
                          (lazy-numbers)))
