--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
I think that's because of the constructors which means GCC can't really
introduce the required copy for the by value passing.
-> C++ FE if A shouldn't be TREE_ADDRESSABLE (I think with defaulted
copy constructor it should stay a "POD"?)
