>Description:
If a directory has permissions drwx------ and I try to change into it without being the owner, then the cd command fails. But pwd thinks I successfully changed into that directory and incorrectly reports as such.
>How-To-Repeat:
$ whoami
roby
$ pwd
/usr/local/etc
$ ls -ld s*
drwx------  2 root  wheel    512 Feb 12 11:30 samba
-rw-r--r--  1 root  wheel   3312 Feb 12 11:34 screenrc
