Additional context

the following is the tsan report: https://pastebin.com/e2TEaq6q

it seems that there is a race condition happened between the following two code section:

Condition::~Condition()
{
    notifier_->will_be_deleted(*this);
}

    auto fill_active_conditions = [&]()
            {
                bool ret_val = false;
                active_conditions.clear();
                for (const Condition* c : entries_)
                {
                    if (c->get_trigger_value())
                    {
                        ret_val = true;
                        active_conditions.push_back(const_cast<Condition*>(c));
                    }
                }
                return ret_val;
            };
