如何在 Google Chrome 中调试选项卡崩溃 [英] How do I debug a tab crash in Google Chrome

问题描述

我们有一个单页应用程序会随机崩溃整个浏览器选项卡.我观察了一个多小时的记忆，但它并没有增加，一切看起来都很好.过了一段时间后，标签突然崩溃了.

We have a single page application that randomly crashes the whole browser tab. I observed the memory for more than an hour but it wasn't increasing and everything looks just fine. Than out of a sudden after some more time passes, the tab crashes.

我在

C:UserscburgdorfAppDataLocalGoogleCrashReports

但是 Chrome-last.dmp 已经完全过时了.是否有任何地方可以查找有关崩溃的其他信息?更何况它是一头难以繁殖的野兽.

but the Chrome-last.dmp is totally outdated. Is there any place where I can look for additional information about the crash? Not to mention it's a hard to reproduce beast.

我想知道我是否可以在连接了 windbg 的情况下启动 Chrome 并等待(2 小时左右 sigh)标签崩溃.这行得通吗?

I wonder if I could start Chrome with windbg attached and wait (2 hours or so sigh) for the tab crash. Would that work?

更新

你们所有人都给出了很好的答案，并为寻找错误提供了有价值的建议.最后，我能够使用以下步骤重现该错误并获得清晰的故障转储:

All of you gave good answers and provided valueable advice for bug hunting. In the end I was able to reproduce the bug and get a clear crash dump using the following steps:

1.) windbg.exe -o chrome.exe
2.) reproduce crash
3.) .dump /ma C:PathToACrashDumpFile.dmp (as Paul pointed out)
4.) end session and load the crash dum with windbg
5.) use !analyze -v to extract valuable information

推荐答案

一旦 WinDbg 入侵，使用此命令创建完整的故障转储:

Once WinDbg breaks in, use this command to create a full crash dump:

.dump /ma C:PathToACrashDumpFile.dmp
