If I add (gc) before the (pk 'heap-size ...), I can't reproduce:
;;; (heap-size 12742656)
;;; (heap-size 12808192)
;;; (heap-size 12808192)
;;; (heap-size 12808192)
;;; (heap-size 12808192)
(another run)
;;; (heap-size 4976640)
;;; (heap-size 8855552)
;;; (heap-size 12029952)
;;; (heap-size 12029952)
;;; (heap-size 12029952)
However, if I increase the number of seconds waited, I can eventually
reproduce some heap growth:
;;; (heap-size 12742656)
;;; (heap-size 12742656)
;;; (heap-size 12808192)
;;; (heap-size 12808192)
;;; (heap-size 12808192)
;;; (heap-size 12808192)
;;; (heap-size 12808192)
;;; (heap-size 12808192)
;;; (heap-size 12808192)
;;; (heap-size 12808192)
;;; (heap-size 12808192)
;; <--- here's the jump
;;; (heap-size 23359488)
;;; (heap-size 23359488)
;;; (heap-size 23359488)
;;; (heap-size 23359488)
;;; (heap-size 23359488)
;;; (heap-size 23359488)
;;; (heap-size 23359488)
;;; (heap-size 23359488)
;;; (heap-size 23359488)
(This is in a "guix shell guile guile-fibers" environment)
Greetings,
Maxime.
