This doesn't seem sufficient; any members that have already been
instantiated will still have the default visibility. If you want to
go this way, you'll need to call reset_type_linkage when changing the
visibility of a type that's already defined.
Is there a reason you can't declare the visibility before the first
use of A<double>, e.g.
extern template struct __attribute ((visibility("hidden"))) A<double>;
followed later by
template class A<double>;
?
