I'm surprised to see that this removal does not cause any regressions. Those lines in gfc_compare_interfaces come from r194622, which apparently was Paul's very first commit to support unlimited polymorphism (back in 2012). I guess the interface checks in compare_type/compare_rank have been refined since then, so that this crutch is not needed any more (in particular since it's wrong ;) Paul, do you agree that the patch in comment 3 is ok to commit?
