Dear Fred, I would say that you're using a buggy gfortran version (http://lists.debian.org/debian-gcc/2009/03/msg00070.html). You may want to check your version with 'gfortran --version' in order to be sure of it. The '-malign-double' switch provides only a slight optimization and as you have already proven, it may be removed with very little impact on performance.
