Reported By: [EMAIL PROTECTED]
Status: Open
Bug Type: Arrays related
Operating System: Digital UNIX V4.0G (Rev. 1530)
PHP Version: 4.2.1
New Comment:
Bug #17257 seems to be the same problem ("Digital UNIX OSF/1" is the
old name of "Compaq Tru64"). People there found that all sort functions
broke with PHP-4.2.0RC1, I can confirm this now.
Smallest test program:
<?php
$a = array(9,7,3,5);
sort($a);
print_r($a);
?>
Output:
Array
(
[0] => 9
[1] => 7
[2] => 3
[3] => 5
)
It's not compiler-related, both gcc-2.95.2 and Compac C V6.3-129 give
the same results. Maybe endianess-related (the Compaq machine have
Alpha processors)?
If somebody more clueful wants to take a look at this problem: Compaq
provides free test accounts (not only with Tru64, but also with
FreeBSD, NetBSD and Linux), see
<http://www.testdrive.compaq.com/>.
I compiled PHP-4.2.0RC1 there on FreeBSD/Alpha, and gcc-2.95.3 gives
lots of warnings:
*** The -O2 flag TRIGGERS KNOWN OPTIMIZER BUGS ON THIS PLATFORM
But even with CFLAGS="-O0 -g" sort() does not sort at all.
On FreeBSD/Intel it does work, so it probably is an endianess problem.

Well,
the script runs fine under my IRIX64 6.5.16m on mod_php/Apache 1.3.24
but not when using a 64bit cgi binary with Apache2.

I checked some older versions:
until PHP-4.1.2, sort() was fine. I didn't check 4.2.0RC*, yet, but
will do so tomorrow.

Updated version according to Michaels tests.

This would be great. I tested it on PHP 4.2.1 on Win2k, it worked fine.
So it seems to be a platform specific problem.
I can help you with testing other versions on that machine/fixing the
bug. It would be nice, if some of the core developers (maybe Andrei,
Andi, Rasmus, Zeev, Jeroen, Derick - these are the people who did most
changes in the last months on array.c) could give us some information
on what files may affect this.
I've found that between 4.0.5 and 4.2.1 nearly the whole source for
PHP_FUNCTION(sort) has changed.

On Digital UNIX V4.0G (Rev. 1530), sort() does not work with PHP 4.2.1,
either. It does work with PHP 4.0.5 on that same platform. Should I try
PHP 4.1.x to see where things started to go wrong?
