Follow-up:The module funcofrho_tfw.F90 is using 6 modules. If I remove the last(which is not mandatory because it is only defining subroutinesinterfaces) the compilation works again. Does anyone have a hint about wether this is or not a bug and wether Ihave to fill or not a bug report (I've not found any bugs like this in the database). --Pierre-Matthieu Anglade
