------- Comment #2 from sfilippone at uniroma2 dot it 2010-01-16 17:05 ------- As mentioned in http://gcc.gnu.org/ml/fortran/2010-01/msg00075.html the code works with Nag; it is not supposed to behave correctly at runtime under gfortran, not until the vtables from fortran-dev are fixed and merged, but it is supposed to compile correctly, and it did until early December (sorry, I don't remember more precisely).
