A simple program with a large array segfaults

["Gowri Kumar CH" <gkumar007 at gmail dot com>]

Greetings,
I'm running gcc on the latest Ubuntu(Edgy) and I get segfault with the
following program:

<snip>
#include <stdio.h>
#include <limits.h>

#define SIZE (INT_MAX>>3)

int main()
{
       int arr[SIZE];
       printf("%d\n",SIZE);
       return 0;
}
</snip>

bash$  gcc --version
gcc (GCC) 4.1.2 20060928 (prerelease) (Ubuntu 4.1.1-13ubuntu5)
Copyright (C) 2006 Free Software Foundation, Inc.

bash$ gcc -Wall arr.c
arr.c: In function 'main':
arr.c:8: warning: unused variable 'arr'

bash$ ./a.out
Segmentation fault (core dumped)

I'm little surprised, why should it segfault. And especially when gcc
doesn't give any error or warning at the time of compilation (I could
use arr[o]=0, to remove the existing warning, but the error still
exists)
