/* File:     big_dims.c
 *
 * Purpose:  Try to change the dimension of an array
 *
 * Compile:  Try 
 *              gcc -g -Wall -o dims dims.c
 *           If this doesn't work, try
 *              gcc -g -Wall -std=c99 -o dims dims.c
 * Run:      ./big_dims
 *
 * Input:    none
 * Output:   messages about the arrays
 *
 * Note:     
 * 1.  A value of dim = 12 consistently causes a seg fault on one
 *     of my MacOS X machines.  You may need to experiment
 *     with different choices of dim to get a seg fault.
