I tested it and it seems to be working! The code compiled with non_overridable on. There are run-time segfaults and array bounds mismatches in our code, that don't happen with ifort, so I will be slowly isolating those and reporting them. They seem unrelated to the non_overridable issue, as they also happen when I remove non_overridable. Ondrej
