No special environment is needed to reproduce this bug.

>Description:

When a directory has the sticky bit set and it is tar'red, sent through
the standard output, the output is caught in a subshell, and untar'red
in a different directory ...

... then the permissions are restored incorrectly on the directory.

I noticed while creating a backup root partition.

>How-To-Repeat:

$ mkdir asdf fdsa
$ chmod 1777 asdf
$ tar cf - asdf | ( cd fdsa ; tar xvf - )
$ /bin/ls -l fdsa
