Lengthy arrays and SIGSEGV

Hi all:

I'm trying to allocate some integer (mpz_t) arrays with hundreds of  
thousands of elements.  However, the following code  with an  
ARRAY_SIZE of 700000 fails, but works with 600000. Changing the  
number of bits being allocated doesn't seem to change the outcome.   
I've configured the library with --disable-alloca to get around the  
stack allocation issue, but I still get a SIGSEGV error from GCC 4.0  
on Apple OS 10.4.3.  Anyone know if it's possible to get a larger array?

#define ARRAY_SIZE 700000
int main (int argc, const char * argv[]) {

	mpz_t test_array[ARRAY_SIZE];
	mpz_array_init(test_array[0], ARRAY_SIZE, 32);
	return 0;

Thanks in advance!
