Here is a much simpler example that crashes as well:

#+begin_src emacs-lisp
(seq-doseq (_ (stream-range 1 1000000)) nil)
#+end_src

Note that this is executed as a loop due how to streams are implemented,
although the definition of `seq-doseq' looks recursive.  But it seems
that gc has a problem with the large number of conses created when
processing that.


Michael.
