Memory leaks in example simpleD3D9Texture

Accelerated Computing CUDA CUDA Programming and Performance

I have some problem with CUDA sdk’s 2.0 sample simpleD3D9Texture. It was compiled in VC++ 2005 without any code changes. I using debug version of DirectX runtime of sdk march 2008. OS Win Vista SP1 x86. Display driver version 177.84. Hardware - 8600GT.

I have many messages in output (in every frame):
First-chance exception at 0x777342eb in simpleD3D9Texture.exe: Microsoft C++ exception: long at memory location 0x0012fbdc…
Direct3D9: (ERROR) :SetViewport failed.
Direct3D9: (ERROR) :dvMaxZ and dvMinZ should be between 0 and 1

And after closing application:

What is the reason?

I also have the same error in WinXP. I’m running CUDA 2.0, VS2008, and DirectX SDK August 2008. Display driver 178.24 on a GeForce 8800 GTS.

Here’s the output:

The program ‘[3484] simpleD3D9Texture.exe: Native’ has exited with code 0 (0x0).

[/codebox]

In fact, I also have the same problem with the following simple code:

[codebox]

// Create the D3D object.

if( NULL == ( g_pD3D = Direct3DCreate9( D3D_SDK_VERSION ) ) )

    return E_FAIL;

// Create the D3D Display Device

D3DPRESENT_PARAMETERS d3dpp; ZeroMemory( &d3dpp, sizeof(d3dpp) );

d3dpp.Windowed              = TRUE;

d3dpp.BackBufferCount       = 1;

d3dpp.SwapEffect            = D3DSWAPEFFECT_COPY;

d3dpp.hDeviceWindow         = g_handles.hwndText;

d3dpp.BackBufferWidth	    = IMAGE_SIZE_X;

d3dpp.BackBufferHeight      = IMAGE_SIZE_Y;

d3dpp.BackBufferFormat      = D3DFMT_UNKNOWN;

d3dpp.PresentationInterval  = D3DPRESENT_INTERVAL_IMMEDIATE;

hr = g_pD3D->CreateDevice (adapter, D3DDEVTYPE_HAL, g_handles.hwndCGH,

                                            D3DCREATE_HARDWARE_VERTEXPROCESSING, 

		&d3dpp, &g_pD3DDevice);

if( FAILED( hr ) )

    return hr;

// CUDA context for this thread must be attached to the same Direct3D device

CUDA_SAFE_CALL( cudaD3D9SetDirect3DDevice(g_pD3DDevice) );

cudaThreadExit();

// destroy the D3D device

SAFE_RELEASE(g_pD3DDevice);

// destroy the D3D object

SAFE_RELEASE(g_pD3D);

[/codebox]

But commenting out the cudaD3D9SetDirect3DDevice line, clears the error. So it seems that either cudaD3D9SetDirect3DDevice adds more D3D references than it should, or that cudaThreadExit doesn’t clear them all. Can anyone confirm this?
