Encountered 3 of the GPU tests terminated abnormally in the middle.

Environment:
- MSVC 2010 Express on Windows 7-64bit
- OpenCV [[OpenCV]] 2.3.0 64-bit build CUDA enabled. (Debug x64)
- opencv_extras-r6194
- CUDA 4.0 (64-bit) + Driver 275.33
- Nvidia graphics hardware GeForce [[GeForce]] 310M (CC 1.2, 512M DDR3)

2 tests crashed:
- meanShift.accuracy
- meanShiftProc.accuracy
Both crashes are related to GpuMat [[GpuMat]] Release() call.

1 test throw assertion
- Nvidia.multitest -> testListernerHaarAppl.invoke()
TestHaarCascadeApplication.cpp:23 [[TestHaarCascadeApplication]].cpp:23

I am not familiar enough with gpu code to understand what exactly cause the crash. If you need more information, please let me know.
