Autotest using with valgrind go wrong

I executed the

./Tools/autotest/ --no-clean --valgrind --debug build.Copter test.Copter

command and encountered [Error 2] No such file or directory:‘arducopter-+ -valgrind.log’

In the developer document, I see that this file should be created by myself after running the command. So I don’t know where the problem is. Does anyone have the same problem。

I haven’t solved this problem yet,upup :face_with_peeking_eye:
