clang does not accept mixed -flto and non-lto CUs and the problem is not
reproducible by this sample code using clang if using -flto for all CUs.
There might be (bigger?) examples where the same issue is triggered by
clang and bigger examples (like systemd on fedora) where I ran into the
bug, but this small example only shows the problem when using gcc and
mixing -flto and non-lto CUs.
