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. ------------------------------------------------------------------------ [2002-05-27 14:29:54] behrens@takenet.de 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.
