Bug description: Reference and global keyword don't work as documented
<?
$a = 1;
$b = 2;
function Sum() {
global $a, $b;
$b = &$a;
}
echo "a=$a b=$b";
?>
I expect echo to output "a=1 b=1" since within Sum I set the variable $b
(which refers to global $b) as a reference to $a.
However, this works using $GLOBALS instead of the keyword global.
