[Message part 3 (text/plain, inline)]

This is with an empty init.el, and the following early-init.el:

D:\...\.emacs.d> type early-init.el
(setq default-frame-alist '((left . (+ 0))))

D:\...\.emacs.d> emacs.exe

lisp.h:1231: Emacs fatal error: assertion failed: FIXNUMP (a)

Setting the same value on init.el works.

Well, that has been working for far too long to be bothered now, I
think.

Done.

It's unused, and was unused since the initial revision of that
function.  I think it's there just to keep the signature compatible
with that of x_window (which itself only keeps that compatibility in
toolkit versions).
