Stefan, I tried running your pi_bench (increasing the numer of iterations by x10 to reduce jitter). The run to run variation exceed the difference between the two versions. Here are the fastest of 7 runs on my machine. i3-2370M CPU @ 2.40GHz ×ばつ 4. linux 64bit. With patch: 1.154152s Without patch: 1.157730s I'm somewhat surprised by the slowdown on your machine. There should be no difference in the bytecodes executed or their implementation in the pi_float loop.
