Hi.
    The first part doesn't cause any problem naturally, but you have to check
if you free parts of that array
    during the program BEFORE shutdown! That's very important, because if you
do and don't set those parts
    back to NULL, it means that at shutdown, you're trying to free areas in
memory that have already been
    freed - which causes a SIGSEV error. So remember, if, at some point, you
free memory - set the pointer
    to NULL.

    Hope this helps.
