I am executing "cat /dev/null" calls in a shell to be sure there i= s an open call. But the syscall.open probe does not fire. I am using Ubuntu 18.04.2 LTS with Systemtap translator/driver (version 4.0= /0.170, non-git sources). I know that this script already worked for me on older versions. Is there a= nything what has changed? Does anyone has an idea why it should not work? Wolfram
