--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Reduced:
```
void f(const int&);

namespace {
  struct myFactory
  {
    static constexpr int s_sList =3D 1;
  };
}
//constexpr int myFactory::s_sList;
void sdi_register_model()
{
  f(myFactory::s_sList);
}
```

If we uncomment the definition, it works.

I think this is correct behavior, just we should produce a better error mes=
sage
of not have the definition and only the declaration here.=
