Thank you for the additional information.
You are right.  This is a regression introduced in Emacs 25.1.

I] Not observed with Emacs-24.5.
II] I reproduce the issue with Emacs-25.1.
*)  I see the issue with Emacs-25.1 even after loading kmacro.el
    from Emacs-24.5.  That seems to point to changes in the
    C source code; maybe some changes in src/macro.c?

I am having some difficulties to do a bisect to track down
changes in macro.c.  Maybe someone can do it much faster and find
the commit causing this issue.
