Description

I was playing today with Ruby profiler and found something strange in my results. Let's take a sample code from docs:

require 'profile'

def slow_method
  5000.times do
    9999999999999999*999999999
  end
end

def fast_method
  5000.times do
    9999999999999999+999999999
  end
end

slow_method
fast_method

Results of methods calls should look like:

0.00     0.19      0.00        1     0.00   100.00  Object#slow_method
0.00     0.19      0.00        1     0.00    90.00  Object#fast_method

But my results are:

35.00     0.15      0.07     5001     0.01     0.03  Object#fast_method
10.00     0.19      0.02     5001     0.00     0.03  Object#slow_method

And it doesn't seem to be proper. Those methods are called once, not 5001 times.
On 1.9.3 everything works fine. And it doesn't look it is a intentional change. But if yes, please enlighten me.

Thanks
