This sample uses a significant MPI_Isend() calls with a dynamically allocated buffer, frees
it as soon as the peer has received the chunk and only then calls MPI_Wait().
This makes the memory inaccessible in MPI_Wait() but happens to
work with most MPI implementations, although it is incorrect. Because it is not
guaranteed that libc actually unmaps the memory chunk, some of the
bytes are modified before free() to trigger an illegal modification
error if the memory is still available.
