I've been trying covert an application which uses DirectSound from C++ to D and have gotten as far as having the app make a call to DirectX at which it crashes with a fatal error.

The call to CreateSoundCapture seems to return successfully with a valid pointer to the IDirectSoundCapture object but calling the objects's CreateCaptureBuffer method (or any other method)causes the app to crash.

Simplfied sourcecode + makefile + dsound.lib import lib is attached
