Thanks for your bug report.  That problem has been fixed in the latest
CVS version of GNU tar <http://savannah.gnu.org/projects/tar/>.

I don't think this is a bug.  Tar 1.13 overwrote the existing
test3.tar, without affecting the parent directory.  But there were
some security problems with this, so the new behavior was instituted.
You can use the --overwrite option to get the old behavior.  But be
careful when using the `--overwrite' option, particularly when
combined with the `--absolute-names' (`-P') option, as this
combination can change the contents, ownership or permissions of any
file on your system.
