janus at gcc dot gnu.org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |janus at gcc dot gnu.org --- Comment #1 from janus at gcc dot gnu.org --- It actually works for me, at least when putting the test case into a .f file. Is it possibly that your file has an f90 extension (meaning it's actually free format)? Would it be a bad idea to introduce a flag like -fline-length-none, which sets the line length both for fixed and free format?
