In Windows, with VS2019 16.7.2 (debug mode) and the default thrust provided with CUDA 11 package, I found this problem:

int main()
{
    thrust::device_vector<int> gpu;
    std::vector<int> cpu;
    gpu = cpu; // assertion in debug
}

The code triggers an assertion in vector:46 (standard vector header, provided by Microsoft) coming from `thrus

The interface for obtaining it ostensibly requires everything to be ready for the actual run - and the documentation does not make it clear what arguments it actually needs and what it's going to do with them (e.g. will it look at the input at all, in any way?
