SIGTRAP Crash when creating a Date from DateComponents with nanosecond >=1 second

[lovetodream]

If you create a Date from DateComponents via Calendar and the DateComponents' nanosecond property is equal to or more than a full second, you'll get a SIGTRAP crash.

Example:

let year = 2023
let month = 8
let day = 27
let hour = 19
let minute = 30
let second = 48
let nanosecond = Int(1.2 * 1_000_000_000) // change 1.2 to anything below 1.0 and it won't crash
var calendar = Calendar(identifier: .gregorian)
calendar.timeZone = TimeZone(secondsFromGMT: 0)!
let components = DateComponents(
    calendar: calendar,
    year: year,
    month: month,
    day: day,
    hour: hour,
    minute: minute,
    second: second,
    nanosecond: nanosecond
)
let value = calendar.date(from: components)

The same code works fine on macOS. Related Swift Forums post: https://forums.swift.org/t/crash-on-linux-when-creating-a-date-from-calendar-date-from-datecomponents/66988

This works with the version of DateComponents in swift-foundation. See also #5001.
