--- Comment #2 from Jason Merrill <jason at gcc dot gnu.org> ---
Bug 52477 deals with the parallel issue for construction. As I mentioned
there, I think the right solution is to handle attribute constructor/destructor
using the C++ __static_initialization_and_destruction mechanism rather than
.{init,fini}_array.
