Description Iker Pedrosa 2021-11-19 08:47:55 UTC

+++ This bug was initially created as a clone of Bug #1986782 +++

This bug was initially created as a copy of Bug #1986111

I am copying this bug because: 
the problem also exists in RHEL9

Description of problem:
When using groupdel with a prefix path, it segfaults on Fedora 34.
groupadd and groupmod both are working fine.

Version-Release number of selected component (if applicable):
shadow-utils-4.6-12.el8.x86_64

How reproducible:
Every time groupdel is executed (as root)

Steps to Reproduce:
1. Create a custom /etc/group file, e.g. using
[root@rhel84-vm ~]# mkdir -p $HOME/custom_root/etc/
[root@rhel84-vm ~]# touch $HOME/custom_root/etc/group
2. Create a group (succeeds)
[root@rhel84-vm ~]# groupadd -P $HOME/custom_root test_group
3. Delete the group (fails)
[root@rhel84-vm ~]# groupdel -P $HOME/custom_root test_group

Actual results:
[root@rhel84-vm ~]# groupdel -P $HOME/custom_root test_group
Segmentation fault (core dumped)

Expected results:
Return code 0 with the group deleted from $HOME/custom_root/etc/group
