That said, 8.x is also quite old in 2024 and perhaps newer major releases have been better at catching regressions?. @tstellar Is there anything a distribution can help to catch such regressions early?

At least for Fedora, we've switched to building clang with clang, so it would be hard to catch this in distribution testing.  Maybe we need some more buildbots to test the versions of gcc we support.
