真机测试使用真机同时加载 7 张以上特殊的 45K的 gif 图会 crash，使用 demo 能复现，但是加载其他的 2M 左右的却不会，怀疑发现了某个特殊 bug。

发现一个问题，使用真机同时加载 7 张以上特殊的 45K的 gif 图会 crash，使用 demo 能复现，url 在下面。

What

有点奇怪45k 的图片为什么会这样，因为线上其他 2M及以上的图片不会出现这个问题。且尝试了 AnimatedImageView 也有概率出现内存过高导致 crash。使用最新版本和 6.3.1 都测试了，都会 crash。

Reproduce

图片 Url: https://cdn.kkyuehui.com/img_10306_187744906.gif?imageView2%2F2%2Fw%2F1200%2Fh%2F1200%2Fq%2F75%7Cimageslim

demo 修改之后的代码如下： class GIFHeavyViewController: UIViewController { let stackView = UIStackView() let imageView_1 = AnimatedImageView() let imageView_2 = AnimatedImageView() let imageView_3 = AnimatedImageView() let imageView_4 = AnimatedImageView()

override func viewDidLoad() {
    super.viewDidLoad()

    stackView.translatesAutoresizingMaskIntoConstraints = false

    view.addSubview(stackView)

    if #available(iOS 11.0, *) {
        NSLayoutConstraint.activate([
            stackView.leadingAnchor.constraint(equalTo: view.safeAreaLayoutGuide.leadingAnchor),
            stackView.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor),
            stackView.trailingAnchor.constraint(equalTo: view.safeAreaLayoutGuide.trailingAnchor),
            stackView.bottomAnchor.constraint(equalTo: view.safeAreaLayoutGuide.bottomAnchor),
        ])
    } else {
        NSLayoutConstraint.activate([
            stackView.leadingAnchor.constraint(equalTo: view.leadingAnchor),
            stackView.topAnchor.constraint(equalTo: view.topAnchor),
            stackView.trailingAnchor.constraint(equalTo: view.trailingAnchor),
            stackView.bottomAnchor.constraint(equalTo: view.bottomAnchor),
        ])
    }

    stackView.axis = .vertical
    stackView.distribution = .fillEqually

    stackView.addArrangedSubview(imageView_1)
    stackView.addArrangedSubview(imageView_2)
    stackView.addArrangedSubview(imageView_3)
    stackView.addArrangedSubview(imageView_4)

    imageView_1.contentMode = .scaleAspectFit
    imageView_2.contentMode = .scaleAspectFit
    imageView_3.contentMode = .scaleAspectFit
    imageView_4.contentMode = .scaleAspectFit

    let url = URL(string: "https://cdn.kkyuehui.com/img_10306_187744906.gif?imageView2%2F2%2Fw%2F1200%2Fh%2F1200%2Fq%2F75%7Cimageslim")
    //https://raw.githubusercontent.com/onevcat/Kingfisher-TestImages/master/DemoAppImage/GIF/GifHeavy.gif

    imageView_1.kf.setImage(with: url)
    imageView_2.kf.setImage(with: url)
    imageView_3.kf.setImage(with: url)
    imageView_4.kf.setImage(with: url)
    //这里循环次数 6 是crash临界点，测试真机是iPhone13。
    for i in 0...6 {
        let imgView = UIImageView()
        imgView.contentMode = .scaleAspectFit
        imgView.kf.setImage(with: url)
        stackView.addArrangedSubview(imgView)
    }
}

}

连接真机后Crash也不会进堆栈信息，而是Xcode 直接弹 Alert 报错：

The app “XXX” on XXX quit unexpectedly. Message from debugger: Terminated due to memory issue

这是内存溢出了，Kingfisher加载gif确实会比较吃内存
