ecco il codice sto compilando con gcc -Wall -o name name.c

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

int *vettore; // vettore globale
vettore = (int *) malloc(1048576 * sizeof(int));

void funz(void);{
for(i=0; i<1048576; i++){
*(vettore+i)=1;
printf("\nvetto[%d]=%d",i,*(vettore+i));
}
//free(vettore);
}

int main(int argc, char **argv){
funz();
return 0;
}
