Bug Summary and Steps to Reproduce

Bug Summary:

Launching a c++ debugger from vscode doesn't launch debugger. For a moment the debugging icons show up, but quickly thedDebugger quits doesn't stopping on breakpoints. No error messages show anywhere in vscode console/problems/output.

Steps to reproduce:

1. Use the default debugger configuration called "g++: build and debug" or configure launch.json like below:

// launch.json
"configurations": [
    {
      "name": "(gdb) Launch 1",
      "type": "cppdbg",
      "request": "launch",
      "program": "${fileDirname}/${fileBasenameNoExtension}",
      "args": [],
      "stopAtEntry": false,
      "cwd": "${fileDirname}",
      "environment": [],
      "externalConsole": false,
      "MIMode": "gdb",
      "setupCommands": [
          {
              "description": "Enable pretty-printing for gdb",
              "text": "-enable-pretty-printing",
              "ignoreFailures": true
          },
          {
              "description": "Set Disassembly Flavor to Intel",
              "text": "-gdb-set disassembly-flavor intel",
              "ignoreFailures": true
          }
      ]
    },
 ]
}

2. From withing vs code debugger tab start the debugger (in the example a configuration "(gdb) Launch 1"
3. Observe how debugger seemingly starts, icons (start/continue/stop) show up for a moment but then disappear and nothing more happens.
4. Inspect how nothing shows up in problems/output/debug console.

Debugger Logs

Nothing shows up anywhere after I enabled logging like hinted ^ above.

Additional Information

I'm using nixos so it might be bit weirder with the linker, I've hit problems before when the linker couldn't find something during compilation. BUT here this is irrelevant: 1) I can compile succesfully with these compilers, also from within vscode. 2) there's no indication whatsover from vscode that anything failed.

Inizia riproducendo il problema con la configurazione launch.json e tasks mostrata, quindi esamina le schede Debugger, Problems, Output e Debug Console mentre utilizzi i percorsi gdb e g++ elencati. Confronta il comportamento con la configurazione predefinita “g++: build and debug”. Il lavoro è completato quando il debugger rimane attivo, si arresta sui breakpoint e segnala un errore utile quando l’avvio non riesce.
