GregorianCalendar(TimeZone*, ...) adopts the zone in the constructor. On U_FAILURE the calendar destructor already deletes that zone. Remove the extra delete tz. The 8.5/master unique_ptr path has the same extra delete after the smart pointer already destroyed the calendar.

There was a problem hiding this comment.
IMO The added test does not exercise the fix.
You see, both constructions succeed, while the removed deletion runs only under U_FAILURE(status). The test produces identical expected output on an affected PHP 8.6.0beta1 build.

The timezone-and-locale IntlGregorianCalendar constructor passes the TimeZone to an adopting ICU constructor. On failure PHP deleted that zone again after delete gcal already ran the calendar destructor.
