[ASTERISK-165] res_calendar_icalendar: SEGV during module refresh
This segfault occurs on proliant, but not on other Debian 12 systems with the same version of libical, interestingly. Asterisk version does not matter.
Not reporting this upstream for now, since this isn't actionable at the moment since it fails to reproduce on any system besides proliant.
