--- Comment #3 from Marc Glisse <glisse at gcc dot gnu.org> 2012-10-15 12:59:15 UTC --- (In reply to comment #2) > Marc, are you aware of this? Yes, attributes don't work so well with templates. This particular case should be fixable, but I'd rather we had a complete plan for vectors that would be as easy to use as std::array. > First blush it seems simple but weird. If you can see how to fix it, please go ahead :-)
