iOS 代号一音频播放崩溃

Question

我注意到我在 iOS 播放音频时出现崩溃。似乎是在 Media 对象上调用 .cleanup() 方法时。

我删除了对清理的调用，但它仍然崩溃，只是需要更长的时间，我假设是在 GC 为运行。

时

代码有点分散，但看起来像：

media = MediaManager.createMedia({path to media}, false);
media.play();
...
media.cleanup();

崩溃时没有堆栈跟踪，但控制台输出如下所示：

<Error>: {app name}(805,0x381b5000) malloc: *** error for object 0x1a122640: pointer being freed was not allocated *** set a breakpoint in malloc_error_break to debug Apr 28 08:53:12 iPod-4 SpringBoard[48] <Warning>: HW kbd: Failed to set (null) as keyboard focus Apr 28 08:53:12 iPod-4 com.apple.xpc.launchd[1] (UIKitApplication:{app package}[0x5cf8][805]) <Notice>: Service exited due to signal: Abort trap: 6 Apr 28 08:53:12 iPod-4 mediaserverd[43] <Notice>: '' {app package}(pid = 805) setting DiscoveryMode = DiscoveryMode_None, currentDiscoveryMode = DiscoveryMode_None Apr 28 08:53:12 iPod-4 SpringBoard[48] <Warning>: Application 'UIKitApplication:{app package}[0x5cf8]' crashed.

似乎是在退出控制媒体对象的表单时或尝试再次播放声音时（通过在同一路径上创建新的媒体对象）。
