[BUG] Memory accumulation when using load_image in a loop

Commencez par exécuter la boucle fournie dans src/main.rs:6 et inspectez le wrapper load_image dans src/image/mod.rs:317, ainsi que le chemin natif af_load_image signalé. Vérifiez si le chargement répété d’images conserve de la mémoire du périphérique et identifiez le comportement pertinent de nettoyage ou de propriété. La tâche est terminée lorsque la reproduction n’accumule plus de mémoire jusqu’à provoquer une erreur de mémoire insuffisante, avec un test de régression pour le chargement répété.

The following program crashed. But why?

use arrayfire::*;

fn main() {
    let mut y =constant!(0 as u8;1);
    for i in 0..1000 {
        let x = load_image::<u8>("2dzs/robot_2dz.png".to_string(), true);
        let z = or(&x, &y, true);
        y = z.copy();
        println!("i={}", i);
    }
    println!("max(y)={:#?}", max_all(&y));
}
