Array Size Limits

[Jack Liddle]

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.
