GCC 12 complains if a reference to an uninitialized object is being passed to a constructor. The mysql_mutex_t, mysql_cond_t would be initialized in the constructor body, which is executed after the initializer list. There is no problem passing a pointer instead of a reference. The wrapper classes do not dereference the pointers in the constructor or destructor, so there does not appear to be any correctness issue.
