--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The problem is that varasm.c uses TREE_PUBLIC on all decls, but it now means
something different on LABEL_DECLs. So either we tweak it:

and wait for other spots that should change, or we choose a different flag.
I think my preference would be to try TREE_PRIVATE bit for it instead.
