From: Operating system: Windows 7 x86 PHP version: 5.4.2 Package: GD related Bug Type: Bug Bug description:Crash in certain script using GD in Moodle
Description: ------------ PHP 5.4.1 and 5.4.2 crashes at a page of learning management system Moodle (http://moodle.org/) drawing a graph using GD. 1. Install Moodle. 2. Log in as admin and create at least one student user. 3. Create a course. 4. Enter edit mode and add a quiz to the course. 5. Log in as a student user, take the quiz just created. 6. Log in as admin, see the quiz report. Page URL is <moodle>/mod/quiz/report.php?id=<module id>&mode=overview. Embedded graph image is rendered by <moodle>/mod/quiz/report/overview/overviewgraph.php?id=<quiz id>. PHP 5.3.8 didn't have this issue. My environment: OS: Windows 7 x86 Home Premium Server package: XAMPP 1.7.7 (Apache 2.2.21, MySQL 5.5.16) PHP: replaced original 5.3.8 with 5.4.1 and 5.4.2 PHP extensions: php_gd2.dll, php_mysqli.dll Moodle: any of 1.9.14, 2.0.8, 2.2.2 Test script: --------------- Tried to reproduce by separating concerning library files only and copied the object properties by var_export but didn't reproduce (graph is displayed without crash). Actual result: -------------- php5ts.dll stops with APPCRASH c0000005. Access to both report page and graph only causes crash. Weirdly if I add "exit();" at the end of the script overviewgraph.php, it doesn't crash.
