如何使用windbg阅读Google Chrome崩溃转储 [英] How to read a google chrome crash dump with windbg
问题描述
-
我打开windbg并说文件 - >符号文件路径：
SRV * c：\code\symbols * http：//msdl.microsoft.com/download/symbols; SRV * c：\code\symbols * https：//chromium-browser-symsrv.commondatastorage.googleapis .com
我猜这是从let到右边的调试符号，最后应该从谷歌那里获取。我从 http://www.chromium.org/developers/how-tos/debugging复制 -
我将崩溃转储拖放到windbg
然后...

此转储文件中存在断点异常。
可以通过.ecxr访问存储的异常信息。
eax = 00000000 ebx = 0038e1f8 ecx = 00000001 edx = 0012df58 esi = 00000002 edi = 0038e218
eip = 776e013d esp = 0038e1a8 ebp = 0038e244 iopl = 0 nv up ei pl zr na pe nc
cs = 0023 ss = 002b ds = 002b es = 002b fs = 0053 gs = 002b efl = 00200246
ntdll！NtWaitForMultipleObjects + 0x15：
776e013d 83c404 add esp，4
0：000& .excr
^'.excr'中的语法错误
你看到它说存储的异常信息可以通过.ecxr访问，但一旦我插入它告诉我，我有一个语法错误。
有谁知道我做错了什么？
你有一个打字错误，它是 .ecxr :)在此期间，另一种简单的方式可以从崩溃转储中获取信息，而不需要太多的WinDbg-fu，是：
。 symfix; .reload
！analyze -v
如果这是一个.NET应用程序（Chromium isn添加这三行
.loadby sos clr
！pe
〜* e！clrstack
here is what I'm trying to solve. I have a crash dump from Google Chrome.
I open windbg and say File -> Symbol File Path: "SRV*c:\code\symbols*http://msdl.microsoft.com/download/symbols;SRV*c:\code\symbols*https://chromium-browser-symsrv.commondatastorage.googleapis.com" I guess this looks for the debugging symbols from let to right and should finally grab them from google then. I copied that from http://www.chromium.org/developers/how-tos/debugging.
I drag and drop the crash dump into windbg
And then...

This dump file has a breakpoint exception stored in it.
The stored exception information can be accessed via .ecxr.

0:000> .excr
^ Syntax error in '.excr'
You see that it says "The stored exception information can be accessed via .ecxr" but once I insert that it tells me that I have a syntax error.
Does anyone know what I'm doing wrong?
You've got a typo, it's .ecxr :) In the meantime, another easy way to get information out of a crash dump without needing too much WinDbg-fu, is:
.symfix; .reload
!analyze -v
And if this is a .NET App (Chromium isn't but just for extra info), add these three lines
.loadby sos clr
!pe
~*e !clrstack
