我试图在（多线程）C ++程序上使用GDB的过程记录和重放功能。在record模式下，GDB不会在我设置的任何断点处中断。如果我不处于record模式，则可以很好地操作GDB（在断点处设置和中断，step / next / continue等）
在这里，我没有设置任何断点，而是尝试在开始录制后简单地continue：
(gdb) record
(gdb) **I hit the Return key here**
The process is already being recorded. Use "record stop" to stop recording first.
(gdb) continue
Continuing.
Couldn't get registers: No such process.
(gdb) Couldn't get registers: No such process.
(gdb) continue
Continuing.
Cannot execute this command while the selected thread is running.
(gdb) info threads

* 5 Thread 0x7facfcc36700 (LWP 161851) "athena.py" (running)
如果设置断点然后continue，我仍然会收到相同的错误消息。 info threads也不显示任何线程都达到了断点（它们都表示为正在运行）。
athena.py是C ++程序的Python接口。众所周知，基本的GDB功能可以与此接口和程序很好地协同工作。
