VSCode remote cpp debug not working

[liushiqi9]

I am using windows 7 and connect to arch using ssh.
I git clone this repo, and tried to use it.
I am able to compile this repo, but when I press F5 to debug it with breakpoint set to line 7.
Things just hang from here. The program is not running. the left top conner has a little blue block running nostop.

I get terminal result:

Executing task: g++ -g main.cpp -o main.out <
Terminal will be reused by tasks, press any key to close it.

With launch.json set to :

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Launch Main",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/main.out",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": true,
            "MIMode": "gdb",
            "logging": {
                "trace": true,
                "traceResponse": true,
                "engineLogging": true
            },
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ],
            "preLaunchTask": "Build Main"
        }
    ]
}

And my debug console has output as following:

@liushiqi9 According to this comment, the issue appears to be with VS Code Insiders and the C++ extension, not VS Code Remote.

This was also reported here for WSL. Closing as a duplicate given this is not related to a sample and is tracked in two other places.
