Description:
------------
Dear PHP Team,

When instantiating a DateTime object with PHP 7.0.0RC4 using PHP CLI, the output systematically
contains "zend_mm_heap corrupted" OR "Segmentation fault (core dumped)".

I'm using the PHP 7.0.0RC4 package provided by ondrej (ppa:ondrej/php-7.0) for Ubuntu. In
addition with the following test script, expected output and actual output, I must say that calling

date_default_timezone_set('Europe/Brussels');

does not help either.

Thanks for fixing it, as we are waiting PHP7.0.0 as the messiah :) !
Thanks a lot also for all your efforts for making PHP better every day!

All the best,
Jérôme Bogaerts



Test script:
---------------
<?php
$date = new \DateTime('2000-01-01');
echo $date->format('Y-m-d') . "\n";

Expected result:
----------------
// -- Expected output is simple as:
2000-01-01


Actual result:
--------------
// -- Output when php.ini's directive date.timezone is commented (using ;)
2000-01-01
zend_mm_heap corrupted
// OR (randomly)
2000-01-01
Segmentation fault (core dumped)


// -- Output when php.ini's directive date.timezone = Europe/Brussels
2000-01-01
zend_mm_heap corrupted
// OR (randomly)
2000-01-01
Segmentation fault (core dumped)
