oh dear! i think i know what happened. self_init has never been called in the first place! it requires a unit argument which i did not give it, so the “alias” to Random.self_init was assigned to nothing, so to speak, instead of calling the function.
Many thanks, Dmitry! I’ve amended that line to let () = Random.self_init () and it works.
