With more recent compilers (gfortran 13.3.0) the baseMgNeutronDatabase_iTest fails. I don't yet know why the compiler causes this, but the reason for the failure in the code is due to not setting the particle to have isMG = .true. . This results in an undefined neutron speed, producing a NaN alpha cross section. This is an easy fix in the tests by adding that line before they begin. We might want to update our tests to include gfortran 13, as well as making some other changes to address resulting compilation warnings.
