Hello,

when we build Python 3.13 with -O3

https://fedoraproject.org/wiki/Changes/Python_built_with_gcc_O3

I see the following annocheck problem:

Hardened: /usr/bin/python3.13: MAYB: test: fortify, reason: -D_FORTIFY_SOURCE=2 detected, expected -D_FORTIFY_SOURCE=3 (lto)

Looks like an annobin issue; do you you have build logs someone can look at?

It first showed up in https://src.fedoraproject.org/rpms/python3.13/pull-request/58

The Ci has all the logs, e.g.

https://kojipkgs.fedoraproject.org//work/tasks/8452/117468452/build.log


The C flags have:

  -Wp,-U_FORTIFY_SOURCE,-D_FORTIFY_SOURCE=3 -O3

Is -D_FORTIFY_SOURCE=3 not comaptible with -O3? Do I need to do somethign about this?

_FORTIFY_SOURCE (any level) should work perfectly with -O (any level).

That's what I thought as well.
