--TEST--
Bug #72622 (array_walk + array_replace_recursive create references from nothing)
--FILE--
<?php
function walk (array $arr) {
array_walk($arr, function (&$val, $name) {
});
return $arr;
}
$arr3 = ['foo' => 'foo'];
$arr4 = walk(['foo' => 'bar']);
$arr5 = array_replace_recursive($arr3, $arr4);
$arr5['foo'] = 'baz';
var_dump($arr3, $arr4, $arr5);
?>
--EXPECT--
array(1) {
["foo"]=>
string(3) "foo"
}
array(1) {
["foo"]=>
string(3) "bar"
}
array(1) {
["foo"]=>
string(3) "baz"
}
