Running JMH with dtraceasm profiler on macOS

[Vsevolod Tolstopyatov]

Hi,

Could you please specify your OS X version, JDK version (or, if it is built
from sources, revision number) and whether this problem reproduces with any
JMH benchmark or with a specific one?

Also, could you please show the output of the "csrutil status" command and
check whether the following command "sudo dtrace -n 'profile-1001 /arg1/ {
printf("%d 0x%lx %d", pid, arg1, timestamp); ufunc(arg1)}'" prints any
errors?

Best regards,
Tolstopyatov Vsevolod
