Yes, you are right, and I was incorrect:

struct servent
{
   char memory[16];
};

int main()
{
    servent * sptr1 = new servent;
    servent * sptr2 = new servent;
    servent * sptr3 = sptr1;
}

----------------
(gdb) p sptr1
$1 = (servent *) 0x804a008
(gdb) p sptr2
$2 = (servent *) 0x804a020
(gdb) p sptr3
$3 = (servent *) 0x804a008

gdb shows the content of the pointer, not the position of the pointer. 
My idiot error... :*)
