Hmm, I see only one important change in this function, between NetBSD 3 
and 4. Call to getgrgid was changed into getgrgid_r in 2005, and this 
stuff went into NetBSD 4.

http://cvsweb.netbsd.org/bsdweb.cgi/src/lib/libutil/passwd.c.diff?r1=1.41&r2=1.42&f=h

getgrgid_r is a reentrant version of getgrgid, which was used before.

This bug may or may not be platform-depended, but on most platforms 
/etc/passwd.conf is populated by sysinst, so this bug is not _that_ easy 
to observe.

I have 3.0.1 installed on my A1200 with 68030, and can't reproduce this 
behaviour (with empty root password and empty /etc/passwd.conf). Also 
tried this on amd64 running 4.0 - no problem there.

Can anyone else running NetBSD 4 on Amiga comment on this problem?

BTW. I stumbled upon interesting fact. If you'll look at CVS log for 
src/lib/libutil/passwd.c, you'll see that similar problem was fixed in 
2005 (rev. 1.39).
