integer overflow in interval.c 358:36

[chongwick]

Description

The following code:

<?php
$now = new DateTime();
$now->setTimestamp(PHP_INT_MAX);
$before = clone $now;
$date = new DateInterval('PT1M');
$date->invert = true;
$date->days = PHP_INT_MAX;
$date->h = PHP_INT_MAX;
$date->i = PHP_INT_MIN;
$date->s = PHP_INT_MAX;
$date->f = PHP_FLOAT_MAX;
$date->y = PHP_FLOAT_MIN;
$date->m = PHP_INT_MAX;
$date->d = PHP_INT_MIN;

$date_sub = date_sub($before, $date);

Resulted in this output:

/home/dan/php-src/ext/date/lib/interval.c:358:36: runtime error: signed integer overflow: -9223372036854775808 * -1 cannot be represented in type 'long long int'

But I expected this output instead:

PHP Version

8.4.2

Operating System

ubuntu 22.04
