So sorting works fine on PHP 4.0.6 on Solaris

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. :-(
