[BUG] Memory accumulation when using load_image in a loop

Comienza ejecutando el bucle proporcionado en src/main.rs:6 e inspecciona el wrapper load_image en src/image/mod.rs:317, junto con la ruta nativa af_load_image indicada. Rastrea si la carga repetida de imágenes retiene memoria del dispositivo e identifica el comportamiento relevante de limpieza o de ownership. Se considera terminado cuando la reproducción ya no acumula memoria hasta producir un error de falta de memoria, y existe una prueba de regresión para la carga repetida.

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));
}
