ID: 43397 User updated by: phajdan dot jr at gmail dot com Reported By: phajdan dot jr at gmail dot com -Status: Feedback +Status: Open Bug Type: Scripting Engine problem Operating System: Linux (Gentoo 2007.0) PHP Version: 5.3CVS-2007-11-25 Assigned To: dmitry New Comment:
Well, I wrote this earlier: I couldn't reduce the set of failing code enough to be usable. I tried again. At some point the problem disappears. It seems to be caused by a big amount of allocation/deallocation, so would be difficult to reproduce in a short script. Please note that the bug has been *introduced* with Zend MM. In earlier versions of PHP it's just not present. That may help finding the cause. I can also try to help reproduce the issue some other way, if you can provide me with some instructions or directions. Previous Comments: ------------------------------------------------------------------------ [2008-02-20 14:50:41] [EMAIL PROTECTED] It is not possible to reproduce and fix the bug, without "bad" code. ------------------------------------------------------------------------ [2008-02-13 18:49:14] phajdan dot jr at gmail dot com Please take a look at my original report - I was unable to extract a simple fragment which is causing the problem. Yet I'm still able to debug the issue in some other way. One thing is worth noting: I'm almost sure it's something withe the new Zend MM introduced in some recent version of PHP. This crash didn't happen earlier (I tested it again with older version just to make sure), and with debug build it also does not happen. ------------------------------------------------------------------------ [2008-02-13 18:45:01] [EMAIL PROTECTED] Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If the script requires a database to demonstrate the issue, please make sure it creates all necessary tables, stored procedures etc. Please avoid embedding huge scripts into the report. ------------------------------------------------------------------------ [2007-11-26 17:55:30] phajdan dot jr at gmail dot com I can confirm the bug with latest CVS snapshot.
