Just to make it a little bit more clear: The stack size limit
need not be increased during compilation, but in the shell where
the program is executed. So, for the sequential program, you should
release the command
        ulimit -s unlimited
in the shell where you start the program, for the parallel program
you should insert it in the login procedure (e.g. in .tcshrc}.
