tm2unixtime.c:458:4 integer overflow

[chongwick]

Description

The following code:

<?php
$v1 = PHP_INT_MIN;
$v4 = new DateTime();
$v4->setDate($v1, 1, 1);

Resulted in this output:

/home/dan/php-src/ext/date/lib/tm2unixtime.c:458:4: runtime error: signed integer overflow: -9223372036854775808 - 1 cannot be represented in type 'long long int'

But I expected this output instead:

PHP Version

PHP 8.4-dev

Operating System

No response

@derickr, implementing proper overflow handling in timelib might be difficult, but it would likely be helpful if the public functions would implement some pre-condition checks (or at least state the pre-conditions) for the supported range of the arguments.
