Brief Issue Summary
Unable to debug on wsl ubuntu any c++ project using remote VSCode gdb
I try to debug perfectly OK executables, which I can manually debug with gdb, but trying to debug on VSCode gives the error attached below, in which every executable return right away with exit code 42.
Couldn't find anything online about this.
The problem reproduces on my machine with the following simple project:
Main.cpp
#include <iostream>
int main()
{
std::cout << "insert x:\n";
int x;
std::cin >>x;
std::cout << "hello x="<< x<< "\n";
}
CMakeLists.txt
cmake_minimum_required(VERSION 3.18.0 FATAL_ERROR)
project(Server)
add_executable(server "Main.cpp")
launch.json

調査の方向性
WSL Ubuntu 上で Main.cpp、CMakeLists.txt、.vscode/launch.json を使って失敗を再現し、手動の gdb と VS Code からの起動を比較します。まず、シェルとデバッガーの終了周辺にある提供されたデバッグログから始め、その後、関連する起動経路を追跡します。VS Code を通じてサンプル実行可能ファイルのデバッグが予期せず終了せずに開始されれば完了です。
