--- Comment #1 from Kleis Auke Wolthuizen <info at kleisauke dot nl> ---
It seems that there is also a problem with regard to
perf_event_create_kernel_counter:

$ stap -v -e 'global s; probe timer.profile { s[backtrace()] <<< 1; } probe end
{ foreach (i in s+) { print_stack(i); printf("\t%d\n", @count(s[i])); } } probe
timer.s(60) { exit(); }' > out.stap-stacks
