我安装了最新的ios sdk 4.3，最新的Monotouch和MonoDevelop更新。创建模板打开GL应用程序（旋转彩色sq）称为TestBug，并在调用draw我得到下面的应用程序输出。应用程序继续运行，但这是我第一次在踩到EagleView.cs中的GL.DrawArrays调用时看到应用程序输出。是否有其他人看到这个或可以告诉我我可能做错了什么？道歉。

Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.

这是MonoTouch中的模拟器唯一错误，该错误已在即将发布的版本中修复。很抱歉给您带来不便。
答案 1 :(得分：0)
我通过全新的机器安装获得相同的行为。在这批调试喷出之后，GL示例应用程序继续正常运行，但我使用线程的真实应用程序无法在iPhone模拟器调试版本中完成加载（无论我在运行它时是否真的在调试器中或不）。
我的应用程序创建了一个线程，在帧循环运行时在后台加载东西，并且线程似乎在UIFont调用中停止。
该应用程序仍然使用发布版本运行，而以前的iOS SDK / MonoTouch组合不会发生这种情况。
这是我用一个全新的硬盘驱动器来解决这个问题：
