/*  The purpose of this program is to use gdb or lldb to watch a
    region of memory get overwritten first with a byte, then a short,
    then an int and finally with a long.

    As can be seen, the program produces no output of its own. Rather,
    use of a debugger is needed.

    The gdb command to examine the memory located at "ram" is:
    x/xg $x1
