aard
     
         (Dutch for "earth") A tool to check memory
        use for {C++} programs, written by Steve Reiss
         (who names his programs after living
        systems).
     
        Aard tracks the state of each byte of memory in the {heap} and
        the {stack}.  The state can be one of Undefined,
        Uninitialised, Free or Set.  The program can detect invalid
        transitions (i.e. attempting to set or use undefined or free
        storage or attempting to access uninitialised storage).
     
        In addition, the program keeps track of heap use through
        {malloc} and {free} and at the end of the run reports memory
        blocks that were not freed and that are not accessible
        (i.e. {memory leaks}).
     
        The tools works using a spliced-in {shared library} on
        {SPARCs} running {C++} 3.0.1 under {SunOS} 4.X.
