My environment is:
```
# uname -a
Linux rpi-rack 6.1.21-v8+ #1642 SMP PREEMPT Mon Apr 3 17:24:16 BST 2023 aarch64 GNU/Linux
# lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description: Debian GNU/Linux 12 (bookworm)
Release: 12
Codename: bookworm
```
I tried to compile my program on Raspberry Pi with clang 14.0.6. It crashes and prints the following (gcc can compile without an issue):
```
