That's exactly what was happening.  The crash was occurring here:

(let ((dir load-path))
  (while dir
    (condition-case nil
        (load (concat (car dir) "/auto-autoloads")) <============
      (file-error nil))
    (pop dir)))

in lisp/prim/loaddefs.el.  The `load' is expected (and supposed) to
fail some of the time.  (This is new code with 20.3-beta8, btw).

Not declaring Ferror_message_string() was apparently the whole reason
behind the crashes.  Compiling with lisp unions is supposed to
generate a typecheck message in that case since such code fails on DEC 
Alphas, but not a crash ...

I don't know.
