--- Comment #2 from Jason Merrill <jason at gcc dot gnu.org> ---
Yes, this behavior is intended; just like you can't explicitly specialize a
class after it's been instantiated, you can't specify attributes either.
The C++ standard is even stricter, saying "No attribute-specifier-seq shall
appertain to an explicit instantiation."
