--- Comment #3 from Dominique d'Humieres <dominiq at lps dot ens.fr> --- > So this is fixed on GCC 6? But not Trunk? (Or more recent releases?) A regression is something working at revision n and broken at revision n+1. Here it seems that a GCC7 revision broke the gfortran and has been backported to GCC6.
