IMHO the correct fix is to not seek and/or truncate the file unless the Fortran semantics require it; that way libgfortran does not need to care whether the file is special or not. As explained in #c23, special files are special in different ways (also different on different OS'es), and trying to enumerate all the ways in which they are special is bound to fail. I think Tobias comment #c24 pinpoints the place which needs to be fixed, but unfortunately I haven't had time to look into it.
