Signed integer overflow in ext/date/php_date.c

[YuanchengJiang]

Description

The following code:

<?php
define("MAX_64Bit", 9223372036854775807);
define("MAX_32Bit", 2147483647);
$otherVals = array(0, 1, -1, 7, 9, 65, -44, MAX_32Bit, MAX_64Bit);
foreach ($otherVals as $otherVal) {
}
$fusion = $otherVal;
$start = new DateTime('2010-06-07');
$interval = new DateInterval('P1D');
foreach (new DatePeriod($start, $interval, $fusion, DatePeriod::INCLUDE_END_DATE) as $day) {
}

Resulted in this output:

/php-src/ext/date/php_date.c:5121:35: runtime error: signed integer overflow: 9223372036854775807 + 1 cannot be represented in type 'long'
