you can read about it here: http://forums.gentoo.org/viewtopic.php?t=43373 to make it short: start this: python -c 'int(10.1); int(10000.3); int(1.2)' on a 'normal' computer, it ends without any output. on the miscompiled pentium4 computers it ends with an overflow error. so basically if it ends with overflow error, gcc broke python because of the march=pentium4. gabor
