[BUG] Memory accumulation when using load_image in a loop

Bắt đầu bằng cách chạy vòng lặp được cung cấp trong src/main.rs:6 và kiểm tra wrapper load_image tại src/image/mod.rs:317, cùng với đường dẫn af_load_image native đã được báo cáo. Theo dõi xem việc tải ảnh lặp lại có giữ lại bộ nhớ thiết bị hay không và xác định hành vi dọn dẹp hoặc ownership liên quan. Được xem là hoàn tất khi bản tái hiện không còn tích lũy bộ nhớ cho đến khi xảy ra lỗi hết bộ nhớ, đồng thời có một regression test cho việc tải lặp lại.

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));
}
