perl was compiled with fastmath support

-ffast-math was one of the options from your -V log that caused me ask how your Perl was configured/built. The other was the -march=pentium2, which is probably perfectly valid, but seems way back level unless it's a very old machine or the -mcpu=athlon-xp requires it?

If your looking at your build configuration, it might be worth questioning these two also.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
