Hi!! Seems like I need to explain the issue a little better.

The file integrity is ok. I can always extract the correct data, but
that's not the point.
The point is there is some garbage at the end of tar, seems like the
garbage are usually ignored but didn't
when used with pipe.

"echo ${PIPESTATUS[*]}" shows the issue about SIGPIPE.
You can also use "tar --ignore-zeros" to see the issue.

We noticed this on gentoo and on exherbo using a strict PM.

Thanks in advice. :-)
