tar: write: Broken pi

[Heinrich Schuchardt]

OpenWRT ChaosCalmer uses busybox 1.23.2.

For many tar.gz files I receive errors like:

user at MR3020:~/src$ wget http://tukaani.org/xz/xz-5.2.2.tar.gz
user at MR3020:~/src$ tar -xzf xz-5.2.2.tar.gz
tar: invalid tar magic
user at MR3020:~/src$ tar: write: Broken pipe

GNU tar on Debian Jessie amd64 has no problem with the same file.

Best regards
