--- Comment #6 from Jason Merrill <jason at gcc dot gnu.org> 2012-02-15 01:22:43 UTC --- The problem here is that there is currently no way to add attributes to a class template instantiation; on the explicit instantiation in your testcase the attributes are just ignored. Wouldn't it be easier to just give test default visibility?
