It doesn't matter which backtrace I get as long as I can see it in the +d3d9
trace.

wine-1.3.23 crashes in the vtable of IDirect3DSurface9, probably the corruption
just being passed on. The code back then just casted the interface field to the
object struct; if it's the wrong interface the object won't be any better and a
crash later on is normal.
