directx bindings problem

[evilrat]

i'm trying directx bindings from dsource 
(http://dsource.org/projects/bindings/wiki/DirectX)
and encountered problem, when calling swap chain getbuffer it 
suddenly crashes. does anyone using it? any help please :(

// Create a render target view
ID3D11Texture2D* pBackBuffer;
	
// C++ version
//hr = g_pSwapChain->GetBuffer( 0, __uuidof( ID3D11Texture2D 
),(LPVOID*)&pBackBuffer );

// D version(crashes)
hr = g_pSwapChain.GetBuffer( 0, &IID_ID3D11Texture2D, 
cast(LPVOID*)pBackBuffer );
