cpptools-srv crashes frequently，(Comes with stack)

[x1ntt]

Environment

• OS and Version: windows11 23H2
• VS Code Version: 1.85.2
• C/C++ Extension Version: 1.23.1
• If using SSH remote, specify OS of remote machine: CentOS7.9

Bug Summary and Steps to Reproduce

Bug Summary:

I didn't find a pattern for its crashes. I only saw "IntelliSense process crashed handle_quick_info" in the output window, and obtained a large number of core files. It crashed very frequently, and each core was 200-300MB in size. I guess it should fill up my hard drive soon.
I need a way to stop this process from generating core files. For example, execute ulimit -c 0 only for this process

Expected behavior:
No Crash.

Configuration and Logs

Sorry, due to development environment limitations, I can't easily get the log file, but I can provide the stack trace

In addition, I would like to ask by the way that there are multiple executable files in my project, so I wrote multiple configurations (such as game and cnet in the configuration file above), but when I edit the code files of the two modules, the configuration does not switch. Is there a way to switch automatically? Or how to configure auto-completion and reference search for multiple executable files in the project?

[sean-mcmanus]

@x1ntt You can use a multi-root workspace, one workspace folder for each executable and each workspace folder can have a different configuration.

[sean-mcmanus]

@x1ntt We're aware of that crash, although the additional crash data might help us. We were tracking it with #12666, but we believe there are multiple causes of the build_sections crash, so we can keep both issues open.

[sean-mcmanus]

@x1ntt I'm not sure how you can configure your OS to stop logging crashes dumps. Our extension isn't creating though dmp files (although cpptools-srv is crashing). You can delete the dmp files.

Are you able to find a sample repro code that repros the issue you can share with us?

Setting the process to generate core is used to track bugs in our project. It is an accident to collect the core of cpptools-srv, but maybe it will be helpful? If there is any information that needs to be obtained from the core, I can provide help (such as specific stack, specific heap variables), can you give me a debug version of cpptools-srv with symbol information, or tell me how to build cpptools-srv (I hope this is cpp development), I can reproduce it 100% here (in fact, it has crashed dozens of times just a while ago, just clicking randomly or waiting for it to analyze the project), but I can't provide the core file (the project I maintain is not open source, nor does it belong to me, the core file may contain the project structure).

For example, how is cpptools-srv started? I can execute ulimit -c 0 before its startup script or parent process starts to suppress the generation of core

I will try to reproduce it using open source projects on my own personal computer, and pay attention to possible clues in existing projects. I will feedback here, or #12666 is also OK.

[x1ntt]

@sean-mcmanus Note: Although version 1.20.0 also crashes, it can completely scan my project, while 1.23.1 can't even completely scan the project

I found a way to reproduce the crash 100% of the time
Trigger by building https://github.com/yanwei1983/luatinkerE/tree/cxx20

Here are the steps

• clone code git clone git@github.com:yanwei1983/luatinkerE.git
• Close vscode, reopen it, and open the project directory
• Download version 5.3.4 from https://www.lua.org/ftp/, https://www.lua.org/ftp/lua-5.3.4.tar.gz
• Unzip lua-5.3.4.tar.gz, unzip it to the luatinkerE/lua folder, and delete src/lua.c and src/luac.c
• Modify CMakeLists.txt to the following content

cmake_minimum_required(VERSION 3.8)
project(luatinkerE)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -g ")

include(CheckCXXCompilerFlag)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++20")
#add_compile_options("-fno-limit-debug-info")

include_directories(lua/src luatinkere tests)

aux_source_directory(luatinkere cur_src)
aux_source_directory(tests cur_src)
aux_source_directory(lua/src cur_src)


link_directories(${CMAKE_CURRENT_SOURCE_DIR}/lua/src)

add_executable(test_runner ${cur_src})
target_link_libraries(test_runner dl)
#target_link_libraries(test_runner liblua.a dl)

• mkdir build, cd build, cmake .., make -j90
• Found code errors, fixed them, and recompiled
• You can see cpp-tools crashing at this point
• When clicking on a variable name in lua_tinker.h, IntelliSense process crash detected: handle_update_intellisense or handle_reference_highlight, handle_completion will appear

I didn't know where the key steps were, so I recorded a video (there were a lot of invalid operations, I was a little nervous :(
