Date: Tue, 18 Jul 2017 20:42:10 +0200

Thanks for checking this so quickly.

It looks like your machine also enters an infinite loop when
evaluating the same form that I posted here:

https://debbugs.gnu.org/cgi/bugreport.cgi?bug=27706#5

I'm not sure where we should patch this issue: in Lisp, in
lib/time_rz.c (which is part of gnulib if I remember right), or in
src/editfns.c (emacs_localtime_rz).  Does anyone have an opinion about
this?
