Qt creator debug remote generic linux occur unable to stop debug

Remote target system arm-linux have cross-compiled and install the sshd and the gdbserver,and they work well.host system build the arm-linux-gdb,Qt version is greater than 5.7.

when click the menu start debuging,the host system can link target via ssh successfully,and at this time ,you can hold breakpoint,and view the  variables.

but ,after this, if you click the menu stop debugger , something show below:

 

User requested stop. Shutting down...

Debugging has finished

Failed to kill remote process: Exit code is 3. stderr: sh: invalid number '--'

sh: invalid number '--'

sh: can't kill pid -528: No such process

sh: can't kill pid 528: No such process

 

the debug log like this :
