bsdtar 1.01.011, libarchive 1.01.013
bsdtar 1.01.020, libarchive 1.01.020

>Description:
bsdtar is unable to archive attached directory.
Looks like both the non-printable character (which was an unicode
char in original name), and some directory depth/name length 
are needed to trigger this bug.
I failed to debug that issue.

>How-To-Repeat:

# tar -xjf libarchivebug.tbz2
# cd libarchivebug
# tar -cf test.tar 1111111111111111111111111111111111111111111111111
archive_write_header_pax: 'x' header failed?!  This can't happen.

GNU tar archive with the problematic path follows.

begin 644 libarchivebug.tbz2
