Edit report at https://bugs.php.net/bug.php?id=73989&edit=1 ID: 73989 User updated by: maxime dot steinhausser at gmail dot com Reported by: maxime dot steinhausser at gmail dot com Summary: PHP 7.1 Segfaults within Symfony test suite Status: Assigned Type: Bug Package: *General Issues Operating System: OS X 10.12.2 PHP Version: 7.1Git-2017-01-24 (Git) Assigned To: laruence Block user comment: N Private report: N New Comment: I confirm your fix is working :) Previous Comments: ------------------------------------------------------------------------ [2017-02-11 05:36:15] laruence@php.net a fix could be: https://gist.github.com/laruence/5c529dd63ed41b7f0621a5858fba662e if you have time, you could test with it. I am not very satisfied with it(change to global struct). will keep think again later. ------------------------------------------------------------------------ [2017-02-11 04:40:55] laruence@php.net yes, they are series problems, but all caused by the same root reason. ------------------------------------------------------------------------ [2017-02-10 17:24:45] maxime dot steinhausser at gmail dot com Thanks for the update. Note that the reproduce script you wrote does reproduce the issue using PHP 7.1.1, but doesn't using PHP 7.1.0. So it might not be the only issue as the Symfony test suite actually fails for this version too. ------------------------------------------------------------------------ [2017-02-10 09:18:34] laruence@php.net a simple produce script is: class Cycle { private $thing; public function __construct() { $obj = $this; $this->thing = function() use($obj) {}; } public function __destruct() { ($this->thing)(); } } for ($i = 0; $i < 10000; ++$i) { $obj = new Cycle(); } echo "OK\n"; ------------------------------------------------------------------------ [2017-02-10 09:14:11] laruence@php.net this is a complicated bug, relates to gc addtional_buffers implementation limit.... I need more time to think... :< ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
