--- Comment #13 from ibuclaw at gcc dot gnu.org ---
Confirmed, D is doing NRVO return whereas C++ isn't.

gdc-11 codegen of the `visible` method:

---
struct Visibility visible (struct AggregateDeclaration * const this)
{
  return <retval> =3D this->visibility;
}
---

vs. gdc-mainline
---
struct Visibility visible (struct AggregateDeclaration * const this)
{
  <retval> =3D this->visibility;
  return <retval>;
}
