Edit report at https://bugs.php.net/bug.php?id=70864&edit=1 ID: 70864 Comment by: fabian at tag1consulting dot com Reported by: eric at ericstern dot com Summary: new DateTime in __construct() crashes Status: Open Type: Bug Package: Reproducible crash Operating System: Centos 7 PHP Version: 7.0.0RC6 Block user comment: N Private report: N New Comment: Note: I tested it on Ubuntu. I did miss that its only crashing on Centos 7. Previous Comments: ------------------------------------------------------------------------ [2015-11-05 21:54:44] fabian at tag1consulting dot com FWIW: The test script works for me on latest PHP-7.0 git checkout. ------------------------------------------------------------------------ [2015-11-05 20:39:40] eric at ericstern dot com 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! ------------------------------------------------------------------------ [2015-11-05 20:34:24] eric at ericstern dot com 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) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=70864&edit=1
