stack walk fail: current thread changes after break

Bug type: Debugger

Describe the bug

• OS and Version: ubuntu 18.04
• VS Code Version: 1.61.2
• C/C++ Extension Version: 1.7.1
• Other extensions you installed (and if the issue persists after disabling them):
• A clear and concise description of what the bug is : The current thread changes right after break causing the command stack-list-frames to fail.

To Reproduce
Embedded linux kernel debugging

Reproduzca el caso de depuración del kernel de Linux embebido descrito en el issue, centrándose en el evento de detención del breakpoint, el comando stack-list-frames y el error de cambio de hilo notificado. Siga el procesamiento del depurador para el hilo 10 y verifique que el recorrido de la pila se realiza correctamente después de un breakpoint sin informar de que el hilo seleccionado está en ejecución.
