--- Comment #3 from Jason Merrill <jason at gcc dot gnu.org> ---
This was fixed recently, perhaps by
* decl2.c (decl_maybe_constant_var_p): References qualify.
* constexpr.c (non_const_var_error): Handle references.
* init.c (constant_value_1): Always check decl_constant_var_p.
* cp-gimplify.c (cp_fold_maybe_rvalue): Don't fold references.
* error.c (dump_decl_name): Split out from dump_decl.
