Yeah, this is what I suspected: that Wine had some reference counting
differences with Windows that provoked this error.

Best would be to write a 'DDraw' test (integrated in the test suite) to be
able to check reference counting in some 'standard' cases (surface creation,
D3D object creation, ...).

Well, as we call a DDraw 'method' to create the surface, you should add the
AddRef call there. For the release, it should be in the 'final_release' call
for the surface (AFAIK, each surface already stores a pointer to its parent
DDraw object).
