Non-numeric pager_id causes a loop that just won't stop

If pager_id is isset but not numeric,

    for ($i = 0; $i <= $this->options['id'] || $i < count($pager_page_array); $i++) {
      $pager_page_array[$i] = empty($page[$i]) ? 0 : $page[$i];
    }

from views_plugin_pager_full.inc

causes a fatal error due to memory limit because count($pager_page_array) is always one ahead (the non-numeric index).

Could be fixed in views or views_content, patch for views_content to make sure the value is numeric. Could also add validation to assure it.
