Comment 1 NBrack 2009-05-01 21:13:12 UTC

I've been mistaken in cut and paste command to reproduce it.
it is plugdev and not plugdev2, of course

I can reproduce this bug on amd64.

Starting program: /usr/sbin/groupmems -g plugdev -a root

Program received signal SIGSEGV, Segmentation fault.

Comment 3 Sebastian Luther (few) 2009-05-02 06:29:27 UTC

With =sys-apps/shadow-4.1.3:

groupmems -g plugdev2 -a root
groupmems: group 'plugdev2' does not exist in /etc/group
