This is basically the same as the the previous Patches, [ZF-9586], [ZF-9467], [ZF-9584]

i cleaned the method as well for speed.

Uncleaned Before Patch

        if ((null !== $name) && isset($this->_elements[$name])) {
            return $this->getElement($name)->getMessages();
        }

        if ((null !== $name) && isset($this->_subForms[$name])) {
            return $this->getSubForm($name)->getMessages(null, true);
        }

        $arrayKeys = array();
        foreach ($this->getSubForms() as $key => $subForm) {
            $array = $this->_getArrayName($subForm->getElementsBelongTo());
            if (!empty($array)) {
                if ($name == $array) {
                    return $subForm->getMessages(null, true);
                }
                $arrayKeys[$key] = $subForm->getElementsBelongTo();
            }
        }

Cleaned After Patch

        if (null !== $name) {
            if (isset($this->_elements[$name])) {
                return $this->getElement($name)->getMessages();
            } else if (isset($this->_subForms[$name])) {
                return $this->getSubForm($name)->getMessages(null, true);
            }
            foreach ($this->getSubForms() as $key => $subForm) {
                if ($subForm->isArray()) {
                    $belongTo = $subForm->getElementsBelongTo();
                    if ($name == $this->_getArrayName($belongTo)) {
                        return $subForm->getMessages(null, true);
                    }
                }
            }
        }

The relevant changes for !$subForm->isArray() and interferences between Name and elementsBelongTo chain

Before Patch

         foreach ($this->getSubForms() as $key => $subForm) {
            $fMessages = $subForm->getMessages(null, true);
            if (!empty($fMessages)) {
                if (array_key_exists($key, $arrayKeys)) {
                    $fMessages = $this->_attachToArray($fMessages, $arrayKeys[$key]);
                    $messages = array_merge($messages, $fMessages);
                } else {
                    $messages[$key] = $fMessages;
                }
         }

And After Patch

         foreach ($this->getSubForms() as $key => $subForm) {
            $merge = $subForm->getMessages(null, true);
            if (!empty($merge)) {
                if (!$subForm->isArray()) {
                    $merge = array($key => $merge);
                } else {
                    $messages[$key] = $fMessages;
                    $merge = $this->_attachToArray($merge,
                                                   $subForm->getElementsBelongTo());
                }
                $messages = array_merge_recursive($messages, $merge);
             }
         }

And finally the patch
