>Description:
pax-as-tar does not appear to detect the premature end of a tar
archive, no warning or error is issued.

this is bad.

>How-To-Repeat:
I did the following:

# tar cf sparc64.tar sparc64
# tar tf sparc64.tar > /dev/null
(all is OK)

# dd if=sparc64.tar of=broken.tar bs=1024k count=10
# tar tf broken.tar > /dev/null
(all still appears OK)

# gnutar tf broken.tar > /dev/null
gnutar: Unexpected EOF in archive
gnutar: Error is not recoverable: exiting now
