Description
While reproducing #8587, I also noticed the following crash in Icinga DB. This happened while triggering a bug involving undefined behavior, so this might as well be some secondary effect, but that's not immediately obvious for me, so I'm opening this to not forget about this.
icinga2: /usr/include/boost/smart_ptr/intrusive_ptr.hpp:199: T* boost::intrusive_ptr<T>::operator->() const [with T = icinga::CheckResult]: Assertion `px != 0' failed.

The cluster has two master nodes, the crash happened on the primary one, i.e. the config master and the one against which the API queries were executed. It had the following notifications configures:

apply Notification "dummy-host-notification" to Host {
