When I evaluate the following form in "emacs -Q":

   (progn
     (switch-to-buffer (get-buffer-create "test"))
     (insert "the first line\na ")
     (let ((o (make-overlay (point) (point))))
       (overlay-put
        o 'after-string
        (propertize (concat "very very very very very very very very "
                            "very very very very very very very very "
                            "long line") 'face '(:background "cyan"))))
     (insert "\nand the last line")
     (previous-line))

and then press C-p, point unexpectedly fails to move. However, when I
then press C-a C-n C-p C-p, the second C-p works as expected.

I've checked in a fix.  Thanks for noticing the problem.
