in `void RenderCore::SetMaterials( CoreMaterial* mat, const int materialCount )` under `RenderCore_Optix7`, the `hostMaterialBuffer` is initialized with size `materialCount`, but `materialBuffer` has size `materialCount` and attribute `ON_DEVICE` set. This triggers `if (location & ON_DEVICE) CopyToDevice();` and eventually performs memcpy with size `(materialCount + 512) * sizeof(CUDAMaterial)`, which can occationally trigger access violation during tinyapp startup.
