英文:
Visual Studio 22 - Asan - Failed to use and restart external symbolizer
问题
我正在尝试为Visual Studio 2022设置Asan地址检查器。我正在按照MS的此指南操作：https://learn.microsoft.com/en-us/cpp/sanitizers/asan?view=msvc-170#ide-msbuild
我成功（大部分，我认为是）按照说明操作了。
但是在运行Asan代码时，我收到了以下警告：
==14676==WARNING: Failed to use and restart external symbolizer!
#0 0x7ff67ec8109f in main C:\Users\Vader\source\repos\AsanTest\AsanTest\main.cpp:5
#1 0x7ff67ec81f68 in invoke_main D:\a\_work\s\src\vctools\crt\vcstartup\src\startup\exe_common.inl:78

#3 0x7ff67ec81d7d in __scrt_common_main D:\a\_work\s\src\vctools\crt\vcstartup\src\startup\exe_common.inl:330

#6 0x7ffe563226b0 in RtlUserThreadStart+0x20 (C:\Windows\SYSTEM32\ntdll.dll+0x1800526b0)
说明中提到要执行4个操作：
0. 启用地址检查器 ✅
1. 关闭编辑并继续 ✅
2. 关闭/RTC1（运行时检查） ✅ 通过右键单击字段并删除值来关闭RTC1。
3. 关闭/INCREMENTAL（增量链接） ✅
当我执行“从开发者命令提示符使用AddressSanitizer”时，我没有收到此警告。
测试代码
#include <stdio.h>
int x[100];
int main() {
printf("Hello!\n");
x[100] = 5; // Boom!
return 0;
}

I am trying to setup Asan Address Sanitizer for Visual Studio 2022. I am following this guide from MS: https://learn.microsoft.com/en-us/cpp/sanitizers/asan?view=msvc-170#ide-msbuild
I was able to (mostly, I think) follow the instructions.
But I get this warning when running my code with Asan.
==14676==WARNING: Failed to use and restart external symbolizer!
#0 0x7ff67ec8109f in main C:\Users\Vader\source\repos\AsanTest\AsanTest\main.cpp:5

#6 0x7ffe563226b0 in RtlUserThreadStart+0x20 (C:\Windows\SYSTEM32\ntdll.dll+0x1800526b0)
The instructions say to do 4 things:
0. Enable Address Sanitizer ✅
1. Turn off edit and continue ✅
2. Turn off /RTC1 (runtime checks) ✅ Turned off RTC1 by right clicking on the field and deleting the value.
3. Turn off /INCREMENTAL (incremental linking) ✅
When I do the "Use AddressSanitizer from a developer command prompt" I do not get this warning.
The test code
#include <stdio.h>
int x[100];
int main() {
printf("Hello!\n");
x[100] = 5; // Boom!
return 0;
}

问题之前已经被提出。

该问题与Visual Studio调试环境相关。在Visual Studio中运行的相同程序会输出警告"Failed to use and restart external symbolizer"，但在cmd中不会。
在项目的属性->调试->环境中有以下内容：
PATH=C:\Program Files\Microsoft Visual Studio22\Community\VC\Tools\MSVC.36.32532\bin\HostX86\x86;%PATH%
ASAN_SYMBOLIZER_PATH=C:\Program Files\Microsoft Visual Studio22\Community\VC\Tools\MSVC.36.32532\bin\HostX86\x86
删除这个变量，警告就会消失。

The problem has been asked before.

The problem is related to the Visual Studio debugging environment. The same program running in visual studio will output a warning Failed to use and restart external symbolizer,but not on cmd.
There is
PATH=C:\Program Files\Microsoft Visual Studio22\Community\VC\Tools\MSVC.36.32532\bin\HostX86\x86;%PATH%
ASAN_SYMBOLIZER_PATH=C:\Program Files\Microsoft Visual Studio22\Community\VC\Tools\MSVC.36.32532\bin\HostX86\x86
in Project's properties-> Debugging->Environment.
Remove the variable and the warning disappears.
