ID: 27229 User updated by: dodell at sitetronics dot com Reported By: dodell at sitetronics dot com Status: Open Bug Type: Reproducible crash Operating System: FreeBSD 5.1-RELEASE-p13 PHP Version: 4.3.4 New Comment:
My arrays were too large; updating refcount from a ushort to a ulong has fixed my problem -- except, the question remains, why's it dumping core in FreeBSD 5.x and not in 4.x? Previous Comments: ------------------------------------------------------------------------ [2004-02-13 03:15:52] [EMAIL PROTECTED] I couldn't reproduce this on ANY system I tried. Linux with 4.3.2, 4.3.3 and 4.3.5dev, freebsd (4.9) with 4.3.5dev... all work fine, valgrind shows nothing (on Linux)... no clue what'sgoing on. ------------------------------------------------------------------------ [2004-02-13 02:35:48] dodell at sitetronics dot com This snapshot does not fix the problem. Again, the application works under the same environment using PHP 5 beta 4. Derick asked me off the record to try this on a FreeBSD 4.x system. test# php -q test.php PHP Notice: Undefined index: ae in /usr/home/dodell/ test.php on line 28 PHP Notice: Undefined index: ai in /usr/home/dodell/ test.php on line 29 PHP Notice: Undefined index: ai in /usr/home/dodell/ test.php on line 30 PHP Notice: Undefined offset: 65535 in /usr/home/ dodell/test.php on line 37 Array ( ) php in free(): warning: chunk is already free php in free(): warning: chunk is already free These problems continue to persist with the latest development version. ------------------------------------------------------------------------ [2004-02-12 20:50:09] [EMAIL PROTECTED] Please try using this CVS snapshot: http://snaps.php.net/php4-STABLE-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-STABLE-latest.zip Cannot replicate using latest CVS. ------------------------------------------------------------------------ [2004-02-12 14:33:29] dodell at sitetronics dot com This code does essentially the same operations as the code I'm using and produces the same error.

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 possible, make the script source available online and provide an URL to it here. Try avoid embedding huge scripts into the report. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
