You need to manage the string storage on your own; dense_hash_map doesn't do 
that for you. (Nor does STL hash_map or similar.) For example, this code has a 
"dangling pointer" bug:

hash_map<char*, char*> m;
{
  char tmp[10];
  tmp[0] = 'a';
  tmp[1] = '\0';
  m[tmp] = tmp;
}
puts(m["a"]);

By the way, tools such as valgrind and purify can find most bugs like these.
