--- Comment #2 from afernandez at odyhpc dot com --- Hi Thomas. That was a good guess but it's not the problem. The flag '-ffree-line-length-none' is already on and there are many other long lines in the code. The compilation completes when the openacc directives are deactivated so it's something specifically related to openacc. Thanks.
