[support] Rendering form instead of individual fields exhausts memory

[Jeff Greenberg]

I have the following in a custom module

function email_subscription_block_view($delta) {
  $content = '';
  switch ($delta) {
    case 'subscribe':
      $content = drupal_get_form('email_subscription_form');
  }
  $subject = NULL;

  return array('subject' => $subject, 'content' => $content);
}

function email_subscription_theme() {
  return array(
    'email_subscription_form' => array(
      'arguments' => array('form' => NULL),
      'render element' => 'form',
      'template' => 'block--email-subscription',
    ),
  );
}

function email_subscription_form($form, &$form_state) {
  $form['email'] = array(
    '#type' => 'textfield',
    '#size' => 15,
    '#maxlength' => 128,
    '#required' => TRUE,
  );

  $form['submit'] = array(
    '#type' => 'submit',
    '#value' => t('sign up'),
  );

  $form['#theme'][] = 'email_subscription_form';

  return $form;
}

In my template I have the following:

<div id="email-subscription">
  <form id="email-subscription-form" class="email_subscription_form form">
    <?php print render($form['email']);?>
    <?php print render($form['submit']);?>
  </form>
</div>

With this the two elements of the form render properly. If, instead I have:

<div id="email-subscription">
  <form id="email-subscription-form" class="email_subscription_form form">
    <?php print render($form);?>
  </form>
</div>

I get a wsod and the log saying memory was exhausted.
