Comment(by nomeata):

 My observation is that with `-kc1M`, thinks work great (37 MB memory in
 use). With `-kc786k` I can already observe the bad memory behaviour, but
 it still finishes (15251 MB). `-kc512k` almost immediately fills up my
 memory.

 My guess is that for some reason, unused stack chunks are not freed by the
 GC.
