Segmentation Fault with Visual Studio 2022 on GitHub Actions Windows Runners - using C++ thread

pthom commented 2 weeks ago

Describe the bug

I have encountered a segmentation fault when running a simple async program compiled with Visual Studio 2022 in release mode on GitHub Actions Windows 2022 runners.

To Reproduce

Ready to use repro

Step by step instructions

Use the following C++ code in your repository:

main.cpp

#include <future>
#include <cstdio>

int main() {
    auto handle = std::async(std::launch::async, []() { return 1; });
    int r = handle.get();
    printf("Result: %d\n", r);
}

Use the following CMakeLists:

cmake_minimum_required(VERSION 3.5)
project("study_ci_thread_fault")
set(CMAKE_CXX_STANDARD 17)
add_executable(main main.cpp)

Use the following GitHub Actions workflow:

name: ci

on: [workflow_dispatch, push, pull_request]

jobs:
  build:
    runs-on: windows-2022
    steps:
      - uses: actions/checkout@main
      - name: Build and Test
        shell: bash
        run: |
          mkdir build
          cd build
          cmake ..
          cmake --build . --config Release
          ./Release/main.exe

Observe the segmentation fault during the test execution.

Expected behavior The async program should run without crashing.

Actual Behavior The program crashes with a segmentation fault.

Runner Version and Platform

windows-2022 (aka windows-latest)

OS of the machine running the runner? Windows

Job Log Output

Run ./build/Release/main.exe
  ./build/Release/main.exe
  shell: C:\Program Files\Git\bin\bash.EXE --noprofile --norc -e -o pipefail {0}
Result: 1

The issue was fixed while I was studying it. Closing...

I didn't see how it was fixed, did they revert the version update in runner-images :thinking:

I don't know. I did not receive any information about the fix.
