使用 AVFoundation.AVPlayer 时，我的应用程序有时会发生崩溃。它是随机发生的，例如当用户更改视频的位置或播放/暂停视频时。我不知道如何修复它，因为崩溃似乎发生在 MonoTouch 层中。

您可以在下面看到崩溃日志。

首先，是什么意思：System.ArgumentException: GCHandle value belongs to a different domain？我试图谷歌它，但我发现没有任何帮助。

此外，该行MonoTouch_AVFoundation_AVPlayer_TrampolineAVCompletionHandler可能表明我在构建设置中设置的蹦床数量有问题：

-aot“ntrampolines=4048”“nimt-trampolines=4048”

也许我应该增加这个数字，但有人知道我们可以设置的限制是多少？如果我增加这个数字会有什么后果？性能/内存问题？
