我正在尝试获取 GDB 跟踪，如另一个问题中所述。 为了完整起见，我在一个终端上运行：
$ gdbserver :1234 ./a.out
Process ./a.out created; pid = 13610
Listening on port 1234
另一位（客户）：
$ gdb ./a.out
...

这就是它与其他问题的不同之处，当我想继续到 9 处的断点时，我收到错误：
Continuing.

Target returns error code '01'.
我尝试了整个实验没有跟踪点，并且继续命令工作正常。
当然，我尝试用谷歌搜索错误代码 01，但似乎很通用，所以我无法得出任何结论。知道可能出了什么问题吗？
