Thanks to your privately provided example I was able to solve that (though
it still won't link due to missing symbols, but that is not the linker's
fault and probably also the reason why the external linker fails as well).
I still don't understand why the object file contained a COMDAT field with
an invalid selection of 0, but it seems that other linkers ignore that as
well... 🤷‍♀️
