Bug: https://bugs.gentoo.org/864412 Signed-off-by: Eli Schwartz <eschwartz93@gmail.com> Signed-off-by: Sam James <sam@gentoo.org> and commit fe5777553eb7e9cf64c0526ba194b831cb455f38 Author: Sam James <sam@gentoo.org> Date: Sat Jul 27 23:19:33 2024 +0100 x11-libs/fox: filter LTO Has strict aliasing issues. The website has: > Tentative alias_cast() template may be used for shutting up GCC alias warnings. This means type-punning related warnings are now properly suppressed. which isn't promising. Signed-off-by: Sam James <sam@gentoo.org> In the latter commit, I should have added -fno-strict-aliasing too.
