4.2.0RC1 introduced the new sorting code Zend/zend_qsort.c from
Sterling, maybe that's related?

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.
