byte-code: Wrong type argument: number-or-marker-p, (+ -21)

[Jan Nieuwenhuizen]

I want to start my emacs with geometry 80x[full-screen-height], with
menu-bar and tool-bar disabled.

With emacs (21.3.1 and also) today's CVS, there is a problem running
emacs without -q, disabling the tool-bar and having it use the full
screen height.

The problem occurs when the emacs window is taller than the screen, at
the time of disabling the tool-bar (this is what we need to get full
screen height after disabling menu-bar and tool-bar).

Here is my .emacs.el pruned for testing:

    (when (equal emacs-major-version 21)
      (tool-bar-mode -1))

    (message "hi")

Then, starting emacs as:

    emacs --geometry 80x100+0-0&  # too tall for my screen, but ok for testing

prints this error:

    byte-code: Wrong type argument: number-or-marker-p, (+ -520)

After hitting this error emacs exhibits some seemingly unrelated
problems, such as gud not syncing the src window.

Running with --debug-init does not help, adding (setq debug-on-error
t) to ~/.emacs.el yields:

    Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p (+ 
-21))
      frame-notice-user-settings()
      command-line-1(("80x100+0-0"))
      command-line()
      normal-top-level()

however, there is no call to number-or-marker-p in
frame-notice-user-settings.  I'm confused.

This is using:
    GNU Emacs 21.3.1 (i386-pc-linux-gnu, X toolkit) of 2003-10-31 on raven, 
modified by Debian
or
    GNU Emacs 21.3.50.2 (i686-pc-linux-gnu, GTK+ Version 2.2.4) of 2003-11-12

Greetings,
Jan.
