--- Comment #4 from Peter Allin <peter at peca dot dk> ---
Aha. When I let perf start the test program, like this:

  perf stat -e probe_testprog:func1 -e probe_testprog:func2 -a timeout 1s
./testprog

The counts are equal (+/- 1 of course).

This make the SystemTap problem and the perf problem look like the same.
Pointing towards the kernel I suppose?
