Description
The Direct3DCreate9 returns a pointer to IDirect3D9 structure. However, our type library thinks it returns a IDirect3D9 structure (instead of a pointer to it).
We can also see the inferred type from the API call is busted:

Research direction
Start by locating the type-library definition and API entry for Direct3DCreate9, then compare its declared return type with the IDirect3D9 pointer described in the issue. Done means the type library and inferred API-call type both represent a pointer to IDirect3D9; the payload names no specific file or test to run.
