Issue #21722 may be related to this:

   https://debbugs.gnu.org/cgi/bugreport.cgi?bug=21722

I began noticing unexpected point positions after undo starting with
Emacs 23.1. I cannot reproduce the regression consistently, and it only
occurs sporadically, but I hope that this helps to get to the root cause
of such problems.

All the best!
Markus
