I'm unable to reproduce this in Emacs 28 (on Debian or Macos).  I have
to increase the limit to make it bug out, but then I just get:

Re-entering top level after C stack overflow

So it looks like this has been fixed in a more general way now?  Are you
still able to reproduce the error in Emacs 28?
