windows - 如何使用windbg分析Chrome Aw Snap后的异常

Question

我的网络应用程序中一直出现“Aw Snap”。使用windbg并在How do I debug a tab crash in Google Chrome的帮助下我试图找出问题所在。

到目前为止我已经完成的步骤:

1. 从 Crashes 目录中获取了 .dmp 文件
2. 加载到windbg
3. 设法查看堆栈(使用“k”)
4. 尝试时!analyze 没有显示任何有意义的内容

我需要什么才能看到导致崩溃的模块 如何从这里取得进展？

编辑: 有一个错字。 "!analyze -v" 所做的工作类似于: kb、dd、.exr、.cxr、kv 对于所有 Chrome AwSnappers - !analyze -v 就是您正在寻找的

信息如下...

Use !analyze -v to get detailed debugging information.

当没有定义异常处理程序来处理引发的异常时，将调用 UnhandledExceptionFilter 函数。
