It is very simple to reproduce: 1 overload the DateInterval in a new class. 2 overload the constructor 3 use one of the member variables. [Sat Jul 07 17:46:32 2012] [notice] child pid 5775 exit signal Segmentation fault (11) I tested with PHP 5.4.4 and it is there, but it also exists in PHP 5.3 Test script: --------------- <?php class Crasher extends DateInterval { public function __construct($time_spec) { echo "Yes i did it, with the next statement it gives a segfault\n"; // It doesn't matter if we take the y parameter or any other. $this->y = 3; } } $c = new Crasher('blah'); ?> Expected result: ---------------- Yes i did it, with the next statement it gives a segfault Segmentation fault ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=62500&edit=1
