Infinite recursion: Customize Faces/Basic faces/Default/Height

Infinite recursion: Customize Faces/Basic faces/Default/Height

[jjl]

I'm using GNU Emacs 21.2.1 from Debian 3 r0.

If I customize Faces/Basic faces/Default, adjusting Height (in 1/10
point units) to 140, and then apply the change to the current session,
emacs appears to go into an infinite loop.  The only frame present
clears of all text, and repeatedly resizes between maximised and a
smaller size, until I kill it.

Using scale rather than point size causes the same problem.  Other
options in the group do not cause a problem.

If I change another option in the group, then look in .emacs to see
what customize generated, I find this:

(custom-set-faces
  ;; custom-set-faces was added by Custom -- don't edit or cut/paste it!
  ;; Your init file should contain only one such instance.
 '(default ((t (:stipple nil :background "#ffffff" :foreground "#000000"
 :inverse-video nil :box nil :strike-through nil :overline nil :underline
 nil :slant normal :weight normal :height 164 :width condensed :family
 "adobe-courier")))))


This works fine.  If I then manually change height to 140, emacs has
trouble at
startup:

but I do get the right font, at the right size (14 pt).

Here is the output with --debug-init:
