```

                  char *new_pool = (char *) realloc (string_space, new_size);
                  if (new_pool == ((void *)0))
                    goto out;
                  if (__builtin_expect (string_space != new_pool, 0))
                    {
                      size_t i;
                      for (i = 0; i < nmap; i++)
                        {
                          map[i].alias += new_pool - string_space;
                          map[i].value += new_pool - string_space;
                        }
                    }
                  string_space = new_pool;
```

Hmmm
