Python team, this is http://bugs.python.org/issue1608
(In reply to comment #2) > Python team, this is http://bugs.python.org/issue1608 > Thanks! I have find why we were affected by this bug : CFLAGS is set by the ebuild and so it lack -fwrapv. It seems that we need to enable this for gcc 4.x : In configure.in : # For gcc 4.x we need to use -fwrapv so lets check if its supported if "$CC" -v --help 2>/dev/null |grep -- -fwrapv > /dev/null; then WRAP="-fwrapv" fi I have patched the ebuild and it work flawlessy.

Fixed in python-2.5.2-r5, thanks for reporting.
commit 113415c295d1d178cfc8e1d38e338b7714a1f096 Author: Sam James <sam@gentoo.org> Date: Sat May 10 12:14:44 2025 +0100 dev-lang/python: don't pass -fwrapv * In eff9f43924fc836970b2378d58523388d9246194 (which is in >=3.12), CPython drops adding -fwrapv and instead starts to pass -fno-strict-overflow instead and controls that with a configure flag (--with-strict-overflow). => We shouldn't pass -fwrapv with >=3.12.0 at least. * But also, adding -fwrapv to begin with doesn't seem right, as the build system should add that for us. We started doing that in: commit 6f4cebcf5b631f30baabb9f8e927d6aedcfbdf27 Author: Ali Polatel <hawking@gentoo.org> Date: Tue Jun 24 13:54:16 2008 +0000 Revbump. Append -fwrapv to CFLAGS if we're using gcc-4, #228905. Updated patchset to fix memory issues with unicode objects, #228905. Drop old. (Portage version: 2.2_rc1/cvs/Linux 2.6.25-gentoo-r1 x86_64) (Signed Manifest commit) which got fixed back in Python 2.5 or so! => We didn't need to pass it at all for nearly 20 years. I've dropped it for all Pythons except for 2.7.x (because who cares about that, so many UB fixes then, etc) given it wasn't doing anything.
