in ThreadManager::StopAll() there is item.thread_item_data pointer which was freed (the pointer was pointing to an object with a log_buffer)
but internal Log buffer from item.object was pointing to that object and when thread_tab.clear() was called then the d-ctor was called
and then save_log_and_clear() method was called and tried to use the freed object.
