Microsoft 调试符号不起作用 [英] Microsoft debug symbol don't work

问题描述

我尝试分析一些内存转储.但我堆叠了一些 Microsoft dll (sechost.dll) 的调试符号.我做什么:

I try to analyze some memory dump. But I stack on debug symbols of some Microsoft dll (sechost.dll). What I do:

1) !sym 嘈杂

2) .symfix

3) .sympath

我的 .sympath 是:

Symbol search path is: srv*
Expanded Symbol search path is: cache*;SRV*http://msdl.microsoft.com/download/symbols

4) 分析 -v之后我看到符号加载.但是对于某些符号，我有

4) analyze -v After it I saw symbols loading. But for some symbols I have

......
SYMSRV:  The operation timed out
SYMSRV:  http://msdl.microsoft.com/download/symbols/sechost.pdb/C4FD72A96E384F62A5F796624D37EAB42/sechost.pdb not found
SYMSRV:  C:\ProgramData\dbg\sym\sechost.pdb\C4FD72A96E384F62A5F796624D37EAB42\sechost.pdb not found
DBGHELP: sechost.pdb - file not found
*** ERROR: Symbol file could not be found.  Defaulted to export symbols for sechost.dll - 
DBGHELP: sechost - export symbols
......

当实际分析开始时，我看到:

When actual analyze start I saw:

.....
IMAGE_NAME:  sechost.dll
BUCKET_ID:  WRONG_SYMBOLS
FAILURE_BUCKET_ID:  WRONG_SYMBOLS_80000003_sechost.dll!SubscribeServiceChangeNotifications
.....

我知道我没有这个 DLL 的 PDB.我尝试使用 .reload/f sechost.dll 加载它.但是分析卡在同一个地方.如何处理?也许有可能增加连接超时或其他方式来获得我需要的东西?

I understand that I don't have PDB for this DLL. I try load it with .reload /f sechost.dll. But analyze got stuck on same place. How to deal with this? Maybe there is possibility to increase connection timeout or other way to get what I need?

推荐答案

我问过这个 Microsoft 和 Andy Luhrs 回复我说微软需要 3 天时间来发布新版本的符号/Windows 10 更新.

I asked this Microsoft and Andy Luhrs replied me that Microsoft needs 3 days to publish the symbols for new builds/ Windows 10 updates.

因此，如果您在更新发布后分析转储，请尝试在更新发布 3 天后加载符号.

So if you analyze dumps after updates have been published, try to load symbols 3 days after the update was published.
