podman exec vs attach causes process crash : can't explain note- > pid diff

## Case :

```
podman create \
--name ubuntu24 \
--userns keep-id \
--user 1000:1000 \
--group-add keep-groups \
--device nvidia.com/gpu=all \
--network=host \
--shm-size 8g \
--security-opt label=disable \
--security-opt apparmor=unconfined \
--security-opt seccomp=unconfined \
ubuntu:latest \
bash

podman start ubuntu24
```

## Problem

**podman attach ubuntu24**

```
