#17449 [Com]: sort() does not work

ID: 17449 Comment by: David.Hill@hp.com Reported By: nohn@php.net Status: Critical Bug Type: Arrays related Operating System: Digital UNIX V4.0G (Rev. 1530) PHP Version: 4.2.1 New Comment: I replicated the problem with 4.2.2 on Tru64, but found that it was fixed by replacing Zend/zend_qsort.c with the latest from CVS, version 1.3 (HEAD) I am not getting unaligned accesses. Previous Comments: ------------------------------------------------------------------------ [2002-08-24 05:50:32] derick@php.net Attention! ------------------------------------------------------------------------ [2002-08-24 04:53:03] r@bttr.org This bug still exists in the 4.2.3RC1 version on Compaq Tru64 (OSF1 xxxxxxx V5.1 1885 alpha): My very simple test case: $ar1 = array("k","i","f","o","p","b"); print "unsorted ar1:"; print_r($ar1); reset($ar1); sort($ar1); print "sorted ar1"; print_r($ar1); The results: unsorted ar1:Array ( [0] => k [1] => i [2] => f [3] => o [4] => p [5] => b ) sorted ar1Array ( [0] => k [1] => i [2] => f [3] => o [4] => p [5] => b ) The configure options, taken from further installation on this machine: ./configure --with-mysql --with-xml --enable-ftp --with-pcre \ --with-gd=/usr/local --with-png-dir=/usr/local \ --with-zlib=/usr/local --with-freetype --with-sessions \ --enable-trans-sid --enable-memory-limit Sorry, but I don't understand why this bug is declared as "closed", although sorting doesn't work in this release candicate. :-( ------------------------------------------------------------------------ [2002-06-07 15:03:05] michael.mauch@gmx.de Thanks, I didn't know that. With php4-200206070600, sort() works again, so this bug is solved: bash-2.01$ ./php Unaligned access pid=24680 <php> va=0x14005d27c pc=0x1201ad760 ra=0x1201ad754 inst=0xb4010000 <?php $a = array(9,7,3,5); sort($a); print_r($a); ?> X-Powered-By: PHP/4.3.0-dev Content-type: text/html Array ( [0] => 3 [1] => 5 [2] => 7 [3] => 9 ) I had some problems compiling it on Tru64, though, and the "unaligned access" doesn't look especially pretty, too. I will open a new bug report for these (if nobody else did). Thank you for your help! ------------------------------------------------------------------------ [2002-06-07 12:48:50] mfischer@php.net STABLE != HEAD, you have to try the non-STABLE snapshot. ------------------------------------------------------------------------ [2002-06-07 11:57:04] michael.mauch@gmx.de Still does not sort with php4-STABLE-200206070600. bash-2.01$ php <?php $a = array(9,7,3,5); sort($a); print_r($a); ?> X-Powered-By: PHP/4.2.2-dev Content-type: text/html Array ( [0] => 9 [1] => 7 [2] => 3 [3] => 5 ) ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
