anlauf at gcc dot gnu.org changed: What |Removed |Added ---------------------------------------------------------------------------- Component|fortran |libfortran Last reconfirmed| |2023-04-28 Ever confirmed|0 |1 Status|UNCONFIRMED |NEW --- Comment #1 from anlauf at gcc dot gnu.org --- I also interpret F2018:13.11.3.1 that a value-separator may follow only a name-value subsequence but not immediately the namelist-group-name. This is also what other brands (NAG, Intel, Nvidia) accept. Thus confirmed.
