--- Comment #3 from Filip Kastl <pheeck at gcc dot gnu.org> --- I've just tried this on some older commits but still didn't find a commit without this behavior so I don't have evidence that this is a regression. The oldest commit I know where this behavior is present is r14-5791-g24592abd68e6ef. I'm not sure how I would reduce this. I don't know Fortran so I don't think I could reduce this manually and I also don't know how I would use automated tools to reduce this.
