Unsupported type

[a1phyr]

When I try to parse types from this PDB from Microsoft, a get this error: UnimplementedTypeKind(0xa)

The PDB: https://msdl.microsoft.com/download/symbols/combase.pdb/70E3ECDD8981C0FF8AC67BED63ABECF91/combase.pdb

It does not seem to be documented in https://github.com/Microsoft/microsoft-pdb/ though.
