Hmm, now I changed simple.el like this:

*** /tmp/ediff230416Vp	2016-07-05 23:29:32.557789593 +0200
--- /home/micha/software/emacs/lisp/simple.el	2016-07-05 23:27:12.017360250 +0200

  			(backward-char 1)))
  		 (point)))))
+         (message "%s" newpos)
  	(goto-char newpos)
  	(if (and (> (point) newpos)
  		 (eq (preceding-char) ?\n))

and recompiled it.  After that, the issue is not reproducible anymore at
all; neither with the uncompiled nor with compiled "simple" library.

Seems we won't find out anything useful by debugging on the Lisp level.
