Subject: 24.3; Crashing when setting frames to random colors

I have a Lisp function that is run every time I do M-x compile:

;; choose random colors every time we compile, just for fun
(defun sw-make-random-hex-color-string ()
  "Return a string in the form of #FFFFFF. Choose the number for
   #xffffff randomly using Emacs Lisp's builtin function (random)."
  ;; seed our random number generator: current datetime plus Emacs's
  ;; process ID
  (random t)
  (format "#%06x" (random #xffffff))
  )

(defun sw-randomize-frame-colors ()
  "Change foreground and background colors of the current frame to
random colors."
  (interactive)
  (let 
      (
       (fg-color (sw-make-random-hex-color-string)) 
       (bg-color (sw-make-random-hex-color-string))
       (color-distance #x3fffff)
       )
    (set-foreground-color fg-color)
    (set-background-color bg-color)
    )
  )

I *think* sometimes the color values come out the same and it causes
Emacs to crash. I'm not sure because it's almost instantaneous when I
run compile.

Note that color-distance is unused, a feature I've yet to implement.

Thanks! I’m closing the bug report.
