Strange owner and group in Terminal

[oxoocoffee]

I am running GCC 4 Hybrid R37017. Not sure if this is BFS file system problem or chown chgrp util. After downloading groff tar.gz I try to uncompress it with tar -zxvf groff-1.22.1.tar.gz onto /User/Projects (second BFS partition). After uncompressing I see that running ls -l shows

drwxr-xr-x 1 1000 users 4096 Jan 9 groff-1.22.1

Now running chgrp -R root groff-1.22.1 and than chown -R user groff-1.22.1 changes it to

drwxr-xr-x 1 user 4294267295 4096 Jan 9 groff-1.22.1

now running again chgrp -R root make it as

drwxr-xr-x 1 4294267295 root 4096 Jan 9 groff-1.22.1

back and forth.

One thing. It does changes all files and sub folders to 4294267295 in groff-1.22.1

I've downloaded groff-1.22.1 from ​http://ftp.gnu.org/gnu/groff/groff-1.22.1.tar.gz, but I could not reproduce the issue. I'll assume it has been fixed in the mean time.
