--FILE--
<?php
$array = new ArrayObject([42]);
try {
$array->setIteratorClass(FilterIterator::class);
} catch (TypeError $e) {
echo $e->getMessage(), "\n";
}
foreach ($array as $v) {
var_dump($v);
}
?>

ArrayObject::setIteratorClass(): Argument #1 ($iteratorClass) must be a class name derived from ArrayIterator, FilterIterator given
int(42)
