The systems this bug was noticed where both at the time running
2.4.20 SMP kernels and libc-2.3.2.so.
I noiticed this severe bug when I did a dist-upgrade to sarge on a
woody machine. Installing certain packages (e.g. cron) which
added/changed groups hang for a long time.
I digged into the problem and found out that it is groupadd which
loops when the /etc/group file containes a line of 675 chars (or more)=20
in my case that is 88 users (or more).
It works fine if I shorten the line to 668 chars (87 users).
(The group tested is users.)
I can recreate the problem every time and here is an example shell output f=
rom
such a "recreation" (starting with an empty users-group-line):

[Here everything hangs and top shows that groupadd is using a lot of
CPU and the residient memory for groupadd is growing until the system
runs out of memory]
I have attached strace-outputs for a successfull "groupadd test"=20
(668 chars, 87 users) and one trunkated for the looping "groupadd test"
when the groupfile contained a longer line.
