Hello, Recent ebuilds of mpg123-base (1.32.9-r1 and 1.32.10-r1) fails to build with LTO on. AFAIR, previous build (1.32.9) went great. It's triggered by a Werror, but from gentoo LTO wiki, it should be enabled to avoid runtime issue. Reproducible: Always Steps to Reproduce: 1. build with -flto -Werror=odr -Werror=lto-type-mismatch -Werror=strict-aliasing 2. emerge =mpg123-base-1.32.9-r1 Actual Results: /var/tmp/portage/media-sound/mpg123-base-1.32.9-r1/work/mpg123-1.32.9/src/include/mpg123.h:1118:21: error: type of 'mpg123_seek_frame_64' does not match original declaration [-Werror=lto-type-mismatch] I disabled LTO build for now.

I am also experiencing this issue
Caused by the lfs flags removal: https://github.com/gentoo/gentoo/commit/292006da0e16c60ff4f9592edc2f594e3b4924b3
(In reply to Kostadin Shishmanov from comment #3) > Caused by the lfs flags removal: Don't think we'll be bringing that back given the missing symbols which is worse. Unless someone has a better fix to offer, guess this is due to just get the filter-lto treatment as a safety -- not planning to spend time o that package myself.
The bug has been closed via the following commit(s): https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=fdc41611e455cd5753bae952b16e8fbbf8789121 commit fdc41611e455cd5753bae952b16e8fbbf8789121 Author: Ionen Wolkens <ionen@gentoo.org> AuthorDate: 2025-03-10 14:54:31 +0000 Commit: Ionen Wolkens <ionen@gentoo.org> CommitDate: 2025-03-10 14:56:17 +0000 media-sound/mpg123-base: filter-lto Or at least for now, not really been looked into.

Note that on my 64-bit multilib system, it only occurs when building 32-bit libraries as well. If I limit the filter-lto to only apply for the 32-bit ABI, the build succeeds. I assume x86 systems have the same issue as USE=abi_x86_32 ones.
