--- Comment #4 from Glenn Hyland <Glenn.Hyland at utas dot edu.au> --- Thanks. I'm already at the latest gFortran release for my platform "Ubuntu 16.04.2 LTS". Not prepared at this stage to go to a development version of Ubuntu that would include a newer compiler version. I'm happy to use the workaround that gives me a working solution, and to make a note about the potential problem with pre-6.3.1 versions of the compiler. Thanks for your help.
