curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$html_string = curl_exec($ch);

You curl link seems have many element(large file).

And I am parsing a string(file) as large as your link and encounter this problem.

After I saw the source code, I found the problem. It works for me !

I found that simple_html_dom.php have limit the size you read.

// get html dom from string
  function str_get_html($str, $lowercase=true, $forceTagsClosed=true, $target_charset = DEFAULT_TARGET_CHARSET, $stripRN=true, $defaultBRText=DEFAULT_B     R_TEXT, $defaultSpanText=DEFAULT_SPAN_TEXT)
  {
           $dom = new simple_html_dom(null, $lowercase, $forceTagsClosed, $target_charset, $stripRN, $defaultBRText, $defaultSpanText);
           if (empty($str) || strlen($str) > MAX_FILE_SIZE)
           {
                   $dom->clear();
                   return false;
           }
           $dom->load($str, $lowercase, $stripRN);
           return $dom;
  }

you must to change the default size below (It's on the top of the simple_html_dom.php)
maybe change to 100000000 ? it's up to you.

define('MAX_FILE_SIZE', 6000000);

Did you check if the HTML is somehow encoded in a way HTML DOM PARSER doesn't expect? E.g. with HTML entities like <html> instead of <html> – that would still be displayed as correct HTML in your browser but wouldn't parse.

I asume that you are using curl + str_get_html instead of simply using file_get_html with the URL because of the POST parameters you need to send.

You can use this W3C validator (http://validator.w3.org/#validate_by_input+with_options) to validate the returned HTML, then, once you are sure the result is a 100% valid HTML code you can report a bug here: http://sourceforge.net/p/simplehtmldom/bugs/.
