Passing a BigInt (mpz_t for GMP) array to C

General Usage

Here’s a new problem. Consider the following C code:

#include<gmp.h>

void fibonacci(mpz_t** fibs, unsigned int l) {
	//Set the first two numbers
	if(l > 0) {
		mpz_set_ui(*fibs[0], 0);
	}
	if(l > 1) {
		mpz_set_ui(*fibs[1], 1);
	}
	//Calculate the remaining array
	if(l > 2) {
		mpz_t temp;
		mpz_init(temp);
		for(int k = 2; k < l; k++) {
			mpz_add(temp, *fibs[k-1], *fibs[k-2]);
			mpz_set(*fibs[k], temp);
		}
	}
}

Calling this in Julia works perfectly well up to l=94, but at l=95 the numbers become so large that C has to create new limbs. This crashes Julia with a spectacularly long error message.
