//  Discussion:

//    TEST01 calls F, which has a memory "leak".  This memory leak can be

//
//  Purpose:
//
//    F computes N+1 entries of the Fibonacci sequence.
//
//  Discussion:
//
//    Unfortunately, F only allocates space for N entries.  Hence, the
//    assignment of a value to the N+1 entry causes a memory leak.
