| This problem was created by the upstream commit 78708b7c8c |
| After applying the commit, it will send SIGINT to the process group(-signal_pid). |
| But if we use gdbserver send SIGINT, and the attached process is not a process |
| group leader, then the "kill (-signal_pid, SIGINT)" returns error and fails to |
| interrupt the attached process. |
