| Steps To Reproduce | <?php class Handler { protected $_sp; public function __construct() { $this->_sp = fopen('wrap://lalal', 'a'); } } class Wrapper { protected $_fp; public function stream_close() { die('waa'); } public function stream_open($path, $mode) { $this->_fp = fopen('/tmp/asdf', $mode); return true; } } stream_wrapper_register('wrap', 'Wrapper'); class Manager { public static $stuff; } Manager::$stuff = new stdClass(); Manager::$stuff->Logs = new Handler; | ||||
| Additional Information | the 'die' is only to illustrate that stream_close isn't called.

Fixed, and thanks for your report with excellent reproduce case. |

|
Still causes issues for PHP 5.1 and 5.2. |
|
|
It crashes in PHP 5.1 and 5.2 even without Xdebug, so just ignoring those then. |
