I've recently updated the host OS to the latest Ubuntu LTS so I was
trying to gather details with the system emacs for comparison:
"GNU Emacs 26.3 (build 2, aarch64-unknown-linux-gnu)
of 2020-03-26, modified by Debian"
But I don't seem to be able to get through one iteration. Could it be a
.elc breakage between 26 and master or something else?

Re-entering top level after C stack overflow
I've tried various combinations of:
(setq max-specpdl-size 650)
(setq max-lisp-eval-depth 400)
but I'm mainly just guessing without any concrete idea of what numbers I
should be going for. Any ideas?
