From: Operating system: Mac OS 10.7.2 Server PHP version: 5.4SVN-2011-11-08 (SVN) Package: Reproducible crash Bug Type: Bug Bug description:Segfault when calling class constructor
Description: ------------ This is constantly reproducible on PHP 5.4 (SVN r318919). It does not occur with PHP 5.3. I am using the SilverStripe framework (http://silverstripe.org). The segfault is happening when trying to execute line 41 of sapphire/core/control/ContentController.php (http://svn.simon.geek.nz/silverstripe/sapphire/branches/2.4/core/control/Content Controller.php, $dataRecord = new Page();) when creating a new Signup controller by direct URL access (http://localhost/silverstripe/Signup). The segfault also occurs when simulating a request using the cli (php sapphire/cli-script.php Signup). The backtrace provided is for this case. Test script: --------------- // Signup.php <?php class Signup extends LoginPage_Controller {} // LoginPage.php <?php class LoginPage_Controller extends ContentController { } Expected result: ---------------- The page displays properly, as it does under PHP 5.3 Actual result: -------------- Backtrace from gdb: Program received signal EXC_BAD_ACCESS, Could not access memory.
