A level of indirection is dropped from the SAFEARRAY pointer in the generated .idl file from how it is declared in the .cpp file.

// cpp_attr_ref_satype.cpp
// compile with: /LD
#include "unknwn.h"
[module(name="MyModule")];
[dispinterface, uuid("00000000-0000-0000-0000-000000000001")]
__interface A {
   [id(1)] HRESULT MyMethod ([in, satype("BSTR")] SAFEARRAY **p);
};
