Use this constructor passing std::string::c_str() (and don't forget the 
allocator, interprocess containers need always a valid allocator to 
allocate memory in shared memory):

    basic_string(const CharT* s,
                 const allocator_type& a = allocator_type())

typedef /*...*/ interprocess_string_t;

interprocess_string_t * =
  managed_shm.construct<interprocess_string_t>("name")
    (std_str.c_str(), managed_shm.get_allocator<char>());

Best,
