I've gotten right down to the problem. Has nothing to do with the number of
parameters. One of the parameters is of type VT_VARIANT (0x000c). That variant
type is not supported by the function PyCom_PyObjectFromVariant, which gets
called along the chain of getting the values down to Python. The default case
statement returns E_OUTOFMEMORY if the type can't be converted to a BSTR.
So, obviously PyCom doesn't like a variant of type VT_VARIANT. The object
actually held inside the variant is a SAFEARRAY of 32 elements. Passing it in as
type VT_VARIANT made my C++ clients happy.
So I guess my question becomes how can I change the parameter type so everyone
