refCast error, cyclic fvPatchField

When using cyclic bc on a non-cyclic patch you get:

Attempt to cast type patch to type lduInterface

    From function To& Foam::refCast(From&) [with To = const Foam::lduInterface; From = const Foam::fvPatch]
    in file /home/preston2/mattijs/OpenFOAM/work/develop/OpenFOAM-plus/src/OpenFOAM/lnInclude/typeInfo.H at line 114.

but no information about field, dictionary etc.

Be nice to have a refCast(From& r, const dictionary&) which throws a FatalIOError instead.
