Not to sure what you mean by GCC won't run? Does the program compile and then seg fault when you run it? I ran into a similar problem a few months ago (google for my name and you'll see the posts). Yes there is a limit to the size of your arrays can be when put on the stack. try instead double *A; A = malloc(500000*sizeof(double)); this should declare the array in the main bulk of your memory. Then access A as per usual.
