Did you have tessellation on? The dragon is a part of the bench that uses heavy tessellation. If the tessellators are dedicated hardware, it could be why it crashes there, as kombustor doesn't seem to use tessellation so that part of the GPU doesn't get stressed. If you turn off tessellation in the heaven benchmark and see if it doesn't crash again at that spot then you could definitely pinpoint that as the cause.
