If one specifies one of the `icon-left' or `icon-top' frame
parameters, both need to be specified.  This is not documented in the
Elisp manual.  That is no problem, I will document it.  What is a
problem is that inadvertently forgetting to do so makes Emacs abort.

I did:

[bash2.05b.0 ~ 3 1] cd /home/teirllm/emacscvsdir/emacs/src
[bash2.05b.0 ~/emacscvsdir/emacs/src 3 2] gdb emacs-21.3.50.1

(gdb) run -q --eval '(blink-cursor-mode 0)'
Starting program: /home/teirllm/emacscvsdir/emacs/src/emacs-21.3.50.1
-q --eval '(blink-cursor-mode 0)'

Then:

M-: (make-frame '((icon-left . 0)))

Result:

    Debugger entered--Lisp error: (error "Both left and top icon corners
    of icon must be specified")
      x-create-frame(((visibility) (icon-left . 0)))
      x-create-frame-with-faces(((icon-left . 0)))
      make-frame(((icon-left . 0)))
      eval((make-frame (quote (...))))
      eval-expression((make-frame (quote (...))) nil)
      call-interactively(eval-expression)

Now, this is expected.

What I did not expect is that quitting out of the debugger with `q'
would make Emacs abort.  Is this unavoidable?

Below are an xbacktrace and a backtrace.

Breakpoint 1, abort () at emacs.c:428
