Don't use malloc for windows functions, use HeapAlloc for that.
Also, you should do some error checking to make sure that the memory was
allocated successfully, or this code will segfault.
You forgot to assign the ppeffect pointer to This, i.e. *ppeffect=This.
you'll need to check that ppeffect isn't NULL first, of course.
At least ID3DXBaseEffectImpl_AddRef/Release/QueryInterface (well,
actually only Release) need to be implemented in the same patch as the
interface leaks memory otherwise (one more unnecessary valgrind error).
Last thing, you need to AddRef the device when creating another
reference to it, and Release it on ID3DXBaseEffectImpl_Release. (Though
a device pointer isn't even neccessary yet, so you could also leave it
away)

Best regards,
 Tony
