It's at least a gnu fortran issue: it needs to generate object code in a larger "model" than it currently is. I've never used gnu fortran, but it might accept the -mcmodel=medium option like gcc and generate code sequences for data symbols that don't limit them to the bottom 2GB (or to within 2GB of the involved code, depending on gcc's choices in implementing the model). If it doesn't accept that option, then you'll need to work with the the docs, mailling lists, etc of the upstream gnu fortran project about how to have it generate code for the medium or large data models per the amd64 ABI.
