With version 4.4.x and above you should have a version number. % gfc44 -c a.f90 && head -1 a.mod GFORTRAN module version '0' created from a.f90 on Wed Oct 3 12:50:55 2012 % gfc45 -c a.f90 && head -1 a.mod GFORTRAN module version '4' created from a.f90 on Wed Oct 3 12:51:00 2012 % gfc46 -c a.f90 && head -1 a.mod GFORTRAN module version '6' created from a.f90 on Wed Oct 3 12:51:04 2012 % gfc47 -c a.f90 && head -1 a.mod GFORTRAN module version '9' created from a.f90 % gfc4x -c a.f90 && head -1 a.mod GFORTRAN module version '9' created from a.f90 Do you have more than one version of gfortran installed on the system? It appears as if you are building the module with an older gfortran and trying to use with a newer version.
