tzdb_list
has "unspecified additional constructors", WG21-N4964 [time.zone.db.list]. #4119 added defenses totime_zone
andtime_zone_link
, so we should updatetzdb_list
similarly.This was found by
llvm-project/libcxx/test/std/time/time.zone/time.zone.db/time.zone.db.list/types.compile.pass.cpp
in the upcoming libcxx update that I'm working on. While this isn't a conformance issue, it's better to strengthen our product than weaken their test here.
