Clish crashes with Segmentation fault after running any 'show cloning-group ...' Clish command.
After enabling generation of core dump files for processes with SUID permisssions per sk102130, core dump files for 'CLISH' process were generated in the /var/log/dump/usermode/ directory.

Core dump files from CLISH process contain the following stack:

[Expert@HostName:]# ./gdb /bin/clish clish_dump
