Description:
------------
Since the last php-update I can not POST html-tags inside a string. If I create a simple form within a textarea, after submit var_dump($_POST) outputs just plain-text without the html-tags. As a result of that, all CMS on my server don't work anymore. 

See what I did inside the code-area.

PHP Version 5.1.6-pl4-gentoo

Reproduce code:
---------------
<form action="#" method="post">
  <fieldset style="width: 300px; margin: auto;">
    <legend>A simple form</legend>
    <label for="id_textarea">Input some text with html-tags here</label><br />     
    <textarea id="id_textarea" name="text" rows="10" cols="50"></textarea><br />
    <input type="submit" name="name" value="Submit"/>
  </fieldset>
</form>
<br />
<?php
  if ( isset ($_POST['text']) ){
  	$output  = '<div>' . "\r\n";
    $output .= "\t" . '<h2>The output of $_POST inside a pre-tag</h2>' . "\r\n";
    $output .= "\t" . '<pre style="border: 1px solid #ccc; padding: 5px;">';
    $output .= $_POST['text'];
    $output .= '</pre>' . "\r\n";
    $output .= '</div>' . "\r\n";
    echo($output);
  }
?>

Expected result:
----------------
Output of the string I sent.

Actual result:
--------------
Output of plain-text without html-tags
