Question

我的应用程序对我和几乎所有用户都正常工作，但我的两个用户（都是El Capitan用户）报告了类似但奇怪的崩溃。

这是例外：

Exception Type: EXC_BAD_INSTRUCTION (SIGILL)
Exception Codes: 0x0000000000000001, 0x0000000000000000
Exception Note: EXC_CORPSE_NOTIFY

Application Specific Information:
API MISUSE: Resurrection of an object

这些都是相应的崩溃线程。来自第一个用户：

基本上他们遇到了同样的崩溃，而且它与CoreAudio有关，但我甚至在我的应用程序中都没有使用CoreAudio。我的应用程序中使用声音的唯一地方是我使用NSSound：

[[NSSound soundNamed:@"Pop"] play];

当我将声音归因于NSUserNotification时：

notification.soundName = NSUserNotificationDefaultSoundName;

当我将麦克风输入添加到屏幕录制功能时（mSession是AVCaptureSession）：

AVCaptureDevice *audioDevice = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeAudio];
AVCaptureDeviceInput * audioInput = [AVCaptureDeviceInput deviceInputWithDevice:audioDevice error:nil];
if ([mSession canAddInput:audioInput]) [mSession addInput:audioInput];

但是，这些函数似乎都没有在崩溃报告的任何其他线程中调用过。

我在Chromium上发现了一个非常类似的崩溃报告： https://bugs.chromium.org/p/chromium/issues/detail?id=549667

根据最后一条消息，可能与应用程序运行时拔出的音频设备有关。有人有那个bug吗？我该如何解决？提前谢谢。

我认为可能会有所帮助的一些信息：

我的OS X目标版本是10.8
它正在使用10.11 SDK
正在使用ARC

Answer 1

这似乎是操作系统中的一个错误。在抽出耳机时，Xcode或Chrome或其他一些应用程序可能会崩溃为“HALC_ProxyObjectMap API MISUSE：对象的复活”

“API MISUSE：对象的复活”
