You are right about this, I'm switching back and forth in the version of gcc
and got lost.
But I have run valgrind now. It was the first time, so I don't understand the
result. Is it somehow the fault of my hardware/OS? Here is the output:
valgrind --leak-check=full /opt/gcc-trunk/bin/gfortran -ffree-form
