++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.
