Monotouch 模板 Open GL 应用程序绘制调用生成故障？

Question

我安装了最新的 ios sdk 4.3、最新的 Monotouch 和 MonoDevelop 更新。创建模板开放式 GL 应用程序（旋转的彩色方形），将其命名为 TestBug，并在调用时绘制，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 EagleView.cs 中单步调用 GL.DrawArrays 时看到应用程序输出。有其他人看到这个或者可以告诉我我可能做错了什么吗？为喷出的东西道歉。

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.

Answer 1

这是 MonoTouch 中模拟器独有的错误，已在即将发布的版本中修复。带来不便敬请谅解。

Answer 2

我在全新安装的机器上得到了同样的行为。在这批调试喷出之后，GL 示例应用程序继续正常运行，但是我的实际应用程序（使用线程）无法在 iPhone Simulator 调试版本中完成加载（无论我运行它时是否实际上在调试器中，或者不是）。

我的应用程序创建一个线程，在帧循环运行时在后台加载内容，并且该线程似乎在 UIFont 调用内停止。

该应用程序仍然以发布版本运行，而以前的 iOS SDK / MonoTouch 组合并没有发生这种情况。

以下是我使用全新硬盘来解决此问题的方法：

1. 安装 Snow Leopard。
2. 安装了 Xcode 4.0.1 和 iOS SDK 4.3。
3. 安装Mono 2.6.7和2.10.1
4. 安装MonoDevelop，运行它，并升级到最新版本（2.4.2）
5. 安装MonoTouch（3.2.6）
6. 使用旋转立方体创建默认iPhone项目
7. 在iPhone模拟器上运行，我遇到同样的问题 genpfault提到。
