Emulators are notoriously nasty, but took an extremely brief look at recent commits, and then noticed https://github.com/sarah-walker-pcem/pcem/commit/e1fba7a7b4418e58e8c595619106d7a3df6b4db4. I have a feeling that our RelWithDebInfo CMake release type means that -fno-strict-aliasing doesn't get passed. Sigh, CMake..
The bug has been closed via the following commit(s): https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=f83903b06e8fe76fcb9d3e36d239a0a5f006a1e3 commit f83903b06e8fe76fcb9d3e36d239a0a5f006a1e3 Author: Sam James <sam@gentoo.org> AuthorDate: 2025-03-13 08:58:02 +0000 Commit: Sam James <sam@gentoo.org> CommitDate: 2025-03-13 08:58:30 +0000 app-emulation/pcem: pass -fno-strict-aliasing as upstream intended Using RelWithDebInfo as the CMake release type instead of Release means this flag doesn't get added as upstream intended.
