--- Comment #5 from mirco <mirco.valentini at polimi dot it> --- Thank you Paul, I was trying to follow the Dominique's suggestion and to fix the problem by myself but it was the first time I examined the gfortran's code, and I was still trying to understand its structure. I'm looking forward to see your patch in order to better understand gfortran. Best regards Mirco
