Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug <at> gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

With ZSH (and maybe some option I'm not aware of) you can go up one
directory by typing ".." as a shorthand for "cd ..".  Now I have this
directory tree.

foo/
foo/bar/
foo/baz/
foo/baz/one/
foo/baz/two/

I invoke `shell' and change to foo/baz/.  Now I type

  cd TAB

and the completion shows one/ and two/.  Now I go up one directory with
"..".  Another

  cd TAB

shows again the completions one/ and two/, but I'm in foo/ (as `pwd'
says) now and the correct completions would be bar/ and baz/.

So it seems `default-directory' is only updated with "cd ..", but not
for the shorthand "..".

The same applies if I have an alias xxx="cd foo/bar/baz".  Then

  xxx RET
  cd TAB

will print the completions for the directory I was before.

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/share/emacs/23.0.60/etc/DEBUG for instructions.

The directory tracking code only recognizes some commands such as "cd",
"pushd", and a couple more.  You may want to look into dirtrack.el.

Have you tried using shell-dirtrack-mode?

That's on by default.  Now I try dirtrack-mode as Stefan suggested.

Dirtrack-debug-mode says that my prompt doesn't match dirtrack-regexp,
but that variable doesn't exist.  It seems to be known as dirtrack-list
now.

I configured it to match my prompt, and it seems to work fine.  It's not
too elegant, though...

Tassilo

Closing this since the alternative method provided by dirtrack.el
handles this case.
It is impossible for shell-directory-tracker to know about non-standard
command/aliases such as using ".." to mean "cd ..".

On reflection, I opened #9555 which summarizes the issue.
