Thanks a lot! So what happened is that we cloned function and conlcuded
it executes 0 times, while we want to make call inside that function to
execute 3694 times. I don't think we should clone function we think
will be executed 0 times. What probably can happen is that we are
updating count of the non-specialized (original function) and this comes
out as an roundoff error...
