Test script: https://3v4l.org/mXdWO This appears to affect all versions between 5.5.0 and 7.0.4 Test script: --------------- class Test extends \SplObjectStorage { /** * {@inheritDoc} */ public function attach($object, $data = null) { throw new \RuntimeException('this is a test'); } } $instance = new Test; $object = new \stdClass; $data = ['foo' => 'bar']; $instance[$object] = $data; Expected result: ---------------- A RuntimeException being thrown. Actual result: -------------- No RuntimeException was thrown. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=71851&edit=1
