can anyone tell me, what is wrong with the following loop in Fill:
Vectorization works for float, double and std::complex<float>, but it fails for std::complex<double>.
The remark "read with atomic ordering or volatile read" hints for something, but neither do I know
exactly what, nor do I know how I can resolve the issue.
