It already has a custom marshaller (in dlls/oleaut32/oaidl_p.c). The
question is: should it be called from here?
I would guess that the VT_PTR handling is a incomplete at the moment, since
it appears to only be marshalling the one byte, whereas it should be
marshalling an array of bytes. To be honest, I don't think the VT_PTR case
can marshal anything correctly, without calling the associated proxy/stub
function (custom marshaller).
I probably don't understand enough to answer this question and Ove is
probably the best person to answer this, but I thought I'd give it stab
anyway and see if this makes sense.
