bad DIRECTORY listing from broken symlinks

[3b]

(directory #P"/tmp/bar/") returns (#P"/tmp/") when /tmp/bar is a broken symlink.
same result on various versions from 1.0.32.10 to 1.2.6.28-165c516, all x8664 linux.

on 1.0.25, x8664 linux it returns NIL as expected.

Cannot reproduce, unless these steps are incorrect on creating the broken symlink:

burton@burton-xubuntu:~/sbcl$ cd /tmp
burton@burton-xubuntu:/tmp$ ln -s bar x
burton@burton-xubuntu:/tmp$ ls bar
ls: cannot access bar: No such file or directory
burton@burton-xubuntu:/tmp$ sbcl
This is SBCL 1.2.6.136-428fd6f, an implementation of ANSI Common Lisp.
