On Windows-x64, both AeF-main and AeF-hyperfine-structure calculate incorrect energies in debug-mode builds using MSVC v17.14.9. This happens in both the main branch and on MS-24-Radium-monofluoride-calculations. Specifically, the energies computed after diagonalization are completely wrong. Additionally, the hyperfine structure Hamiltonian also appears to be incorrectly calculated.
Incorrect results from debug executable: 
output from debug executable.log
Correct results from release executable: 
output from release executable.log
Edit with additional notes:
I did upgrade to MSVC 17.14.9 immediately before noticing this, and debug mode has worked in the past -- will check if builds with older versions have this issue.
