From pr44292: "gfortran currently fails if the RECL= is larger than > 2 GB", so the failure seems expected. I recall pr44292. I never got a reply so I could not test the patch. I would highly suggest using unformatted IO for these large data sets. Saves space and runs faster, clearly. Its been a while so I don't know if I can find that old patch. Breaking ABI is also an issue, needing some discussion with the gfortran team.
