use std::sync::atomic::{AtomicU64, Ordering};
use std::sync::Arc;
use std::thread;
fn work() {
    let a: Arc<AtomicU64> = Arc::new(AtomicU64::new(0));
    let b: Arc<AtomicU64> = Arc::new(AtomicU64::new(0));

    let j1 = thread::spawn({
        let (a, b) = (Arc::clone(&a), Arc::clone(&b));
        move || {
            a.store(10, Ordering::Relaxed);
            b.store(20, Ordering::Relaxed);
        }
    });
    let j2 = thread::spawn({
        move || {
            let y = b.load(Ordering::Relaxed);
            let x = a.load(Ordering::Relaxed);
            if (x, y) == (0, 20) {
                panic!("{x},{y}");
            }
        }
    });
    j1.join().unwrap();
    j2.join().unwrap();
}

fn main() {
    loop {
        work();
    }
}

Is it possible for this program to panic?
