Update - this doesn't even need to be in an object's constructor, as I initially
discovered it. Simply <?php new DateTime(); will reproduce the issue!

Description:
------------
Instantiating a DateTime object in a constructor causes an engine crash, printing either
"Segmentation Fault" or "zend_mm_heap corrupted".
This only seems to happen in Centos7 with PHP7RC6 installed from the Webtatic-Testing repo; I can
NOT reproduce it on OS X using the same version installed via homebrew. In that environment, I have
disabled all extensions by renaming /etc/php.d to /etc/php.d.disabled and the crash still occurs.
Originally found under nginx/php-fpm, but happens under cli as well.
I can privately provide access to the server which reproduces this if helpful.
Test script:
---------------
<?php
class X {
private $date;
public function __construct() {
$this->date = new DateTime();
}
}
$x = new X();
var_dump($x);
Expected result:
----------------
object(X)#1 (1) {
["date":"X":private]=>
object(DateTime)#2 (3) {
["date"]=>
string(26) "2015-11-05 20:24:38.000000"
["timezone_type"]=>
int(3)
["timezone"]=>
string(3) "UTC"
}
}
(exit 0)
Actual result:
--------------
object(X)#1 (1) {
["date":"X":private]=>
object(DateTime)#2 (3) {
["date"]=>
string(26) "2015-11-05 20:31:09.000000"
["timezone_type"]=>
int(3)
["timezone"]=>
string(3) "UTC"
}
}
Segmentation fault
(exit 139)
