Thanks, but I should have sent some code in addition to my explanation. 
The above works for me to, but can you please test the code below. That 
code gives the error. The important thing is the newline characters.

(defvar o1 nil)
(defvar o2 nil)
(defun test-me()
  (interactive)
  (let ((buf (get-buffer-create "*OVERLAY Error*")))
    (switch-to-buffer-other-window buf)
    (with-current-buffer buf
      (erase-buffer)
      (insert "123\n\n  890")
      (if o1
          (move-overlay o1 3 5)
        (setq o1 (make-overlay 3 5)))
      (overlay-put o1 'face '(:underline "red"))
      (if o2
          (move-overlay o2 3 9)
        (setq o2 (make-overlay 4 9)))
      (overlay-put o2 'face '(:background "#ffff77"))
      (other-window -1)
      )))

(test-me)
;;(delete-overlay o2)
