有时候会发生一些异常，但异常的堆栈信息中完全找不到我们自己写的源码，这样的异常到底怎么调试！
本文基于 WPF on .NET Framework 4.5
文章一开始，先列出几个异常的前几行。
System.ComponentModel.Win32Exception (0x80004005): Not enough quota is available to process this command.
System.Runtime.InteropServices.COMException (0x80070008): Not enough storage is available to process this command. (Exception from HRESULT: 0x80070008)
System.Runtime.InteropServices.COMException (0x88980411): Exception from HRESULT: 0x88980411
System.OutOfMemoryException: Insufficient memory to continue the execution of the program.
异常堆栈太长了，这里只列出一行，详细的可以看本文文末的“ 附 ”节，免得影响大家阅读。
为什么会发生这些异常？
初步看这些异常，几乎都没有什么头绪，因为根本就不是从我们的代码调用中引发的。所以，如果我们不能接触到发生异常的现场的话，几乎就只剩下搜索这一条路线可走了。
0x80004005: 配额不足，无法处理此命令。
- 问题状态：尚未解决。
- 复现步骤：有一种复现方式，疯狂给某个窗口发送 Windows 消息，这个窗口所在的进程可能会收到此错误。
- 表现现象：但从查阅的资料来看，极有可能是导致窗口不渲染（Window Freezes）。
-
猜测原因：窗口用于储存消息队列的容器存储空间耗尽。

The current process has used all of its system allowance of handles for Window Manager objects

0x80070008: 存储空间不足，无法处理此命令。
- 问题状态：尚未解决。
- 复现步骤：复现一次，但难以总结步骤，其它通过日志搜集。
- 表现现象：从唯一的一次复现来看，会导致整个窗口无法操作，无任何响应。
