VS代码上的简单GDB C++调试失败,出现NullReferenceException

Question

我的来源file.cpp:

#include <iostream>
using namespace std;
int main()
{
    int x = 1;
    int y = 2;
    cout << x + y << endl;
    return 0;
}

我使用编译它g++ -g file.cpp,然后我的launch.json文件是这样的:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(gdb) Launch",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/a.out",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": true,
            "MIMode": "gdb",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
        }
    ]
}

我的目录结构是:

- workspaceFolder
  - .vscode
    - launch.json
  - a.out
  - file.cpp

当我单击Debug选项卡中的绿色"Start debugging"箭头时,我在Debug Console中收到此错误:

Stopping due to fatal error: NullReferenceException: Object reference not set to an instance of an object

我究竟做错了什么？我看过每个教程和调试C++似乎适用于所有这些,除了在我的情况下.我也安装了C/C++(Microsoft)扩展,并运行Ubuntu 64位.

我有同样的问题,不知道为什么,但设置"externalConsole"在launch.json以false奏效了我.

此问题已在 15天前在Microsoft/vscode-cpptools上报告,自v1.30.0以来一直在发生,并且应该在最新的内部人员构建中修复.
