Hi All,

I am using “ruby -r profile prog” for the same program between Windows  
and  
Linux.

I got the different result. In Windows, I got

```
                                  calls

```

9.52 0.35 0.06 865 0.07 0.07  
Module#method\_added

but in Linux, I only got  
calls  
0.00 0.23 0.00 17 0.00 0.00  
Module#method\_added

Do you know why there’s a big different between the two?

Thanks for your help.  
Luan

You are using gems on windows. compare the function lists. Set RUBYOPT  
to empty string before running the program (in a cmd session):
