Thread: Arrays failing to work

Hi all,

I'm having a huge issue over a simple problem. I'm trying to initialize two arrays which are fairly large.

Code:

#include <stdio.h>
#include <stdlib.h>

int main()
{

 unsigned short Projections[336][265][283];
 unsigned short Michelogram[18][18][336][283];

 printf("\n-=<This program ran successfully>=-\n\n");

 return 0;

}

This compiles fine, but when I run it, I get:
Segmentation fault (core dumped)

I've been compiling this snippet on gcc 3.3.2 in Red Hat Linux Fedora core 1. I haven't compiled this on Windows Bloodshed Dev-C++ yet.

What confuses me is that this code below works:

Code:

#include <stdio.h>
#include <stdlib.h>

int main()
{

 /*unsigned short Projections[336][265][283]; */
 unsigned short Michelogram[18][18][336][40];

 printf("\n-=<This program ran successfully>=-\n\n");

 return 0;
}

By getting rid of one array, and toning down the other, it works.

It's almost as if these arrays have a maximum size, or something to that effect. At first, I thought this was a memory issue. The computer I'm running it on is a P3 300MHz w/ 128MB SDRAM. I compiled it on a Dual Xeon 2.4GHz with more RAM, but I still got the same error.

Anyone else have this problem?

Any suggestions would be extremely helpful.

Cheers,
