Yes, I pulled Emacs from the repository, recompiled, restarted and did
the test.

This is my current Emacs version:

GNU Emacs 25.0.50.2 (i686-pc-linux-gnu, GTK+ Version 3.14.5)
 of 2015-05-30 on bebop

Head is now on this commit: 56af96e.

I did the test again, find attached the debug trace.

Thank you for your patience on this.
