segmentation fault on who-can #85

Closed Nightreaver closed 1 year ago

Nightreaver commented 1 year ago

What happened: I'm getting segmentation fault on kubectl rbac-tool who-can create clusterrolebinding

What you expected to happen: print out who can create clusterrolebinding

How to reproduce it (as minimally and precisely as possible): not sure

Anything else we need to know?:
