When parsing iCalendar data | containing a parameterized property, the function passes | icalparameter_compare_kind_map() to bsearch() through an | incompatible comparator function pointer type. bsearch() invokes the | callback through the mismatched type, resulting in undefined | behavior and process termination, leading to denial of service.
