Hi Waldek! Thanks for the rapid answer!
I have: )lisp (lisp-implementation-version) 2.1.11.debian )lisp (sb-ext:dynamic-space-size) 1073741824 )version FriCAS 2022-07-16 compiled at Fr 12 Aug 2022 15:17:27 CEST I'm currently compiling the ECL version. Unfortunately, because of the MacOS problem (https://github.com/sagemath/sage/pull/37041) most sage users won't use the newest FriCAS. So I'll first check whether that makes a difference.
