--TEST--
Bug #72508 (strange references after recursive function call and "switch" statement)
--FILE--
<?php
function a ($option) {
b($option['bla']);
c($option);
var_dump($option);
}
function b (&$string) {
$string = 'changed';
}
function c ($option) {
switch ($option['bla']) {
default:
$copy = $option;
$copy['bla'] = 'copy';
break;
}
}
a(array('bla' => 'fasel'));
?>
--EXPECT--
array(1) {
["bla"]=>
string(7) "changed"
}
