Description:
------------
When using Tidy in PHP5.0.1 instansiating two Tidy objects causes a segfault. This worked successfully in 5.0.0.

Using Tidy snapshot from the 11th of August 2004.

Reproduce code:
---------------
<?php
if (!extension_loaded('tidy')) {
  $prefix = (PHP_SHLIB_SUFFIX == 'dll') ? 'php_' : '';
  dl($prefix.'tidy.'.PHP_SHLIB_SUFFIX);
}

loadContent();
$tidy = new Tidy();

function loadContent() {
  $tidy = new Tidy();
}
?>

Expected result:
----------------
aashley@dt-pc0144 ~ $ php test.php
aashley@dt-pc0144 ~ $

Actual result:
--------------
aashley@dt-pc0144 ~ $ php test.php
Segmentation fault
aashley@dt-pc0144 ~ $
