bug#29070: 26.0.90; emacs-26.0.90 pretest

Hi Noam.

The task is not so easy. When starting emacs "Ffile_attributes" is
called multiple times. I just need to stop the breakpoint when
'Lisp_Object filename' = "/tmp/emacs1000". How coul I code that
condition inside the function?

In the meantime. I have tried the same source code (pretest) on another equal 
machine with
another distro (archlinux). The issue is not present on the archlinux
distro.
