Running dtruss on 10.14.4 (Xcode 10.2) gives me this:

tmp$ sudo dtruss ./ls
dtrace: failed to enable '
 #pragma D option quiet

 ': Failed to enable probe
CSCppMachTaskContainer pid_for_task failed for task 20003, err 5CSCppMachTaskContainer...

This is not a code signing issue (I resigned that ls I'm running). I also already disabled System Integrity Protection so it's not that either. Did anyone see this?
