Bug #63882 (zend_std_compare_objects crash on recursion)
--FILE--
<?php
class Test { public $x = 5; }

$testobj1 = new Test;
$testobj2 = new Test;
$testobj1->x = $testobj1;
$testobj2->x = $testobj2;

try {
    var_dump($testobj1 == $testobj2);
} catch (Error $e) {
    echo $e->getMessage(), "\n";
}

?>
--EXPECT--
Nesting level too deep - recursive dependency?
