bug#29070: 26.0.90; emacs-26.0.90 pretest

[andrés ramírez]

Hi Noam.
> gdb --args ./emacs -Q
> (gdb) run

I have been able of debug it. The error seems to be inside this function. When 
doing M-x
server-start. Any other tip for debugging it?
--8<---------------cut here---------------start------------->8---
  return file_attributes (AT_FDCWD, SSDATA (encoded), Qnil, filename,
                          id_format);
--8<---------------cut here---------------end--------------->8---

Is it ok to pass this code?
--8<---------------cut here---------------start------------->8---
  if (err != 0)
    return unbind_to (count, Qnil);
--8<---------------cut here---------------end--------------->8---
