ID: 38406 Updated by: tony2001@php.net Reported By: zizka at seznam dot cz -Status: No Feedback +Status: Assigned Bug Type: SimpleXML related Operating System: Windows XP PHP Version: 5.1.4 -Assigned To: +Assigned To: helly New Comment: Marcus, please review this patch: http://tony2001.phpclub.net/dev/tmp/bug38406.diff Previous Comments: ------------------------------------------------------------------------ [2007-02-20 12:29:48] dominics at gmail dot com I've just confirmed that this bug works on Linux (Debian Etch) too. Using Apache 2.2.3 and PHP 5.2, and the test case above, the apache process segfaults: [Wed Feb 21 01:26:50 2007] [notice] child pid 3758 exit signal Segmentation fault (11) [Wed Feb 21 01:26:51 2007] [notice] child pid 3938 exit signal Segmentation fault (11) ------------------------------------------------------------------------ [2007-02-20 12:22:05] dominics at gmail dot com I forgot to mention the specific error: Unhandled exception at 0x008eafcb in Apache.exe: 0xC0000005: Access violation reading location 0x00000002. ------------------------------------------------------------------------ [2007-02-20 12:18:58] dominics at gmail dot com While this isn't my bug (and so I can't reopen it), and I can't view the original test case, I still believe I'm experiencing the same crash. I'm using PHP 5.2.1, Apache 2.0.54 and Windows XP. A somewhat similar platform to the original reporter. I am able to consistently reproduce the bug with the following test case: <?php $item = new SimpleXMLElement('<something />'); $item->attribute = 'something'; $item->otherAttribute = $item->attribute; ?> ------------------------------------------------------------------------ [2006-08-18 01:00:01] php-bugs at lists dot php dot net No feedback was provided for this bug for over a week, so it is being suspended automatically.

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. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
