#27229 [Opn->Bgs]: Abort trap (6)

ID: 27229 Updated by: sniper@php.net Reported By: dodell at sitetronics dot com -Status: Open +Status: Bogus Bug Type: Reproducible crash Operating System: FreeBSD 5.1-RELEASE-p13 PHP Version: 4.3.4 New Comment: Not a bug. (PHP5 allows larger arrays though) Previous Comments: ------------------------------------------------------------------------ [2004-02-13 03:51:47] dodell at sitetronics dot com 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? ------------------------------------------------------------------------ [2004-02-13 03:15:52] derick@php.net 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] iliaa@php.net 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.
