Linux with Wine is faster than windowsXP?

[ErV]

Hello.

I've got a computer with two OS'es installed - ASPLinux11 and
WindowsXP SP2.
I've tested recently a super_pi mod 1.4(pi caltulation) on both operating
systems (I've used same Win32 binary file) . It looks like it works faster under Linux, while it
crashes under windowsXP at certain conditions. What's going on?
My friend tried same trick on his computer(taht is much more
powerful). He got slightly different results. IN his case program
works fastr under windows, when calculations aren't very complicated
(pi with 16K digits), but it works faster under linux when calculating "pi" with
1M digits. What's going on? I just want to know if this is a proof of
WindowsXP being slower, or does that mean that there is some
timer-related bug? ASPLinux claims their wine version is 9.5 while
there is mention only about 9.24 version on this site.

Here are timing results and links to original program:

any checksum):
