windbg - 创建子进程并启用 .childdbg 1 时自动继续

问题描述

我正在使用 Windbg 的启动脚本，并且想要调试子进程 (.childdbg 1).但是，一旦启用它，我发现创建子进程时windbg 会自动中断.我不确定为什么会发生这种情况，但这是我正在使用的脚本:

I'm using a startup script for windbg, and would like to debug child processes (.childdbg 1). However, once I enable it, i find that windbg automatically breaks when the child process is created. I'm not sure why this is occurring, but here's the script I'm using:

sxe -c ".echo ********** CLR 1st Chance Exception **********;!pe -nested;.echo ----------- CLRStack ----------;!clrstack;g" clr
sxe -c ".echo Child Process Created;g" cpr
sxe -c ".echo Child Process Exited;g" epr
.load psscor2.dll
.childdbg 1

我通过以下命令调用它:

I'm invoking this via the following command:

windbg.exe -Q -c "$<c:\path\startup.ini" Foo.exe

最后，这是windbg中的输出:

Lastly, here's the output in windbg:

(1d14.191c): Break instruction exception - code 80000003 (first chance)

推荐答案

使用 sxi ibp 忽略初始断点事件您可能还想忽略进程退出 sxi epr

Use sxi ibp to ignore initial breakpoint eventsYou may also want to ignore process exit sxi epr
