我的网络应用程序中一直有“Aw Snap”。使用 windbg 并借助How do I debug a tab crash in Google Chrome我试图找出问题所在。
到目前为止我已经完成的步骤：
- 从崩溃目录得到一个 .dmp 文件
- 加载到windbg
- 设法查看堆栈（使用“k”）
- 尝试 !analyze 时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 就是您要寻找的
以下资料...
