Hi,

I have the following code in c++:

#define TAM 4000
#define NUMPAGS 512

struct pagina 
{
   bitset<12> direccion; 
   char operacion; 
   char permiso;
   string *dato;
   int numero;
}; 

void crearPagina(pagina* pag[], int pos, int dir) 
{
    pagina * paginas = (pagina*)malloc(sizeof(char) * TAM); 
    paginas -> direccion = bitset<12> (dir);
    paginas -> operacion = 'n';
    paginas -> permiso = 'n';   
    string **tempDato = &paginas -> dato;
    char *temp = " ";
    **tempDato = temp;
    paginas -> numero = 0;
    pag[pos] = paginas;     
}

I want to modify the value of the variable called "string *dato" in the struct pagina but, everytime I want to assing a new value, the compiler throws a segmentation fault. In this case I'm using a pointer to string, but I have also tried with a string.

In a few words I want to do the following: pagina -> dato = "test";

Any idea?

Thanks in advance!!!
