[Bug-tar] Extract with ?rwx since 1.14?

[Ralph Sontag]

Hi,
I have a Wireless Router, which has a tar:
BusyBox v1.00-pre2 (2003.08.30-16:40+0000) multi-call binary

If I make a tar archive in the common way with
tar cvf x.tar x
on my computer and transfer it to the router, all works fine with tar 1.13.

But if I use tar 1.14 or tar 1.15.1, it does'nt work:

router# tar tvf x.tar
?rwxr-xr-x 4266/100         0 2005-05-13 21:42:44 x
?rwxr-xr-x 4266/100         0 2005-05-13 21:42:50 x/y
?rw-r--r-- 4266/100         7 2005-05-13 21:42:50 x/y/b
?rw-r--r-- 4266/100         7 2005-05-13 21:42:40 x/a
router# tar xvf x.tar
x
tar: Unrecognised file type
router#

So it seem's, the file format since 1.14 is different!?

My System: Linux SuSE 8.1, the error was first seen on SuSE 9.2
I tried the original sources  ...

Have you any hint's? Can I do some more tests?

Thanks in advance!
        Ralph.
