我可以禁用“无法读取动态函数表条目"吗?WinDbg 中的消息? [英] Can I disable the "Unable to read dynamic function table entry" message in WinDbg?

问题描述

我正在使用一个在运行时生成大量代码的程序，并且似乎没有为其生成任何展开数据.(我没有这个程序的源代码；我正在为它编写一个插件.)

I'm working with a program that generates a lot of code at runtime, and seems not to produce any unwind data for it. (I don't have source code for this program; I'm writing a plugin for it.)

当程序挂起时，我使用 WinDbg 进入它，并尝试使用 ~* k 获取所有线程的堆栈跟踪.除了堆栈跟踪外，我还沿着

When the program hangs, I break into it with WinDbg, and try to get a stack trace for all threads with ~* k. As well as the stack traces, I also get pages and pages (and pages, and more) of messages along the line of

Unable to read dynamic function table entry at 00000000`2450b580

这需要很长时间来打印 - 超过一分钟 - 并且它溢出了滚动缓冲区，所以我丢失了大部分输出.

This takes a long time to print - over a minute - and it overflows the scroll buffer, so I lose most of the output.

我现在已经通过十六进制编辑包含此消息的 DLL 解决了这个问题，但是……说真的.有没有官方的方法来摆脱这条消息?

I've worked around this for now by hex-editing the DLL that contains this message, but... seriously. Is there an official way of getting rid of this message?

我准备好从问题线程中获得糟糕的堆栈跟踪.

I'm prepared for a crappy stack trace from the problem thread(s).

推荐答案

请注意，这是一项安全功能，因此您需要自行承担禁用它的风险.有两种选择:

Note that this is a security feature, so disable it at your own risk. There are two options:

• 如果您知道哪个模块导致了这种情况，您可以将完整路径添加到注册表:HKLM\Software\Microsoft\Windows NT\CurrentVersion\KnownFunctionTableDlls 注册表项
• 您可以使用 .settings set EngineInitialization.VerifyFunctionTableCallbacks=false 禁用它

第二个选项仅在当前会话中禁用它.如果你想让它永久化，你可以用 .settings save 跟随它.

The second option only disables it for the current session. If you want to make it permanent, you can follow it with .settings save.
