The scenario is as follows:

  1. Create an instance of a class (std::map) and sore it as global variable.
  2. Spawn threads.
  3. Threads read and use the same global instance of the class
  4. All spawned threads quit
  5. Global class instance is destroyed

No mutex, no thread modifies the global class instance.

Is it ok?

Thank You
