Bug description:  statement as function parameter gets evaluated after calling the function

Description:
------------
if you use a statement as actual parameter for a function (parameter is
called by reference) the statement get's executed after calling the
function thus overwriting the function's work

Reproduce code:
---------------
function test_array(&$test) {
	$test[] = 2;
}

echo '<pre>';

test_array($test_1);

test_array($test_2 = array(1));

$test_3 = array(1);
test_array($test_3);

print_r($test_1);
print_r($test_2);
print_r($test_3);

echo 'PHP-Version: '.phpversion();
echo '</pre>';

Expected result:
----------------
Array
(
    [0] => 2
)
Array
(
    [0] => 1
    [1] => 2
)
Array
(
    [0] => 1
    [1] => 2
)

Actual result:
--------------
output for version 4.3.11
Array
(
    [0] => 2
)
Array
(
    [0] => 1
    [1] => 2
)
Array
(
    [0] => 1
    [1] => 2
)


output for version 5.1.2
Array
(
    [0] => 2
)
Array
(
    [0] => 1
)
Array
(
    [0] => 1
    [1] => 2
)
