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

Example

// 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);  
};
