Description
What happened?
When I tried creating a deployment in local cluster, which has 50 pods, CRI-O exited with segmentation fault error, and there's no stack trace.
zsh: segmentation fault sudo bin/crio
I tried to debug with dlv, but it didn't show any information other than its exit status.
❯ sudo dlv exec bin/crio

What did you expect to happen?
No segmentation fault happens and CRI-O keeps running.
How can we reproduce it (as minimally and precisely as possible)?
Run CRI-O
Launch local kubernetes cluster.
sudo rm -rf /tmp/*
sudo rm -rf /var/run/kubernetes
export CGROUP_DRIVER=systemd
export CONTAINER_RUNTIME=remote
export CONTAINER_RUNTIME_ENDPOINT=unix:///var/run/crio/crio.sock
export FEATURE_GATES=""
cd ~/kubernetes/kubernetes
./hack/local-up-cluster.shCreate the deployment
