Yes, that (-mcmodel=medium) is the solution. Thanks!

The code has several large arrays, the total size of which exceeds
2GB.
Is this a linker issue, a gcc fortran issue, or a pebkac?
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.
