Description:
------------
Situation:
- magic_quotes_gpc/runtime are OFF in php.ini
- magic_quotes_runtime is ON in php-script

When I get a XML file from a URL with the code below, I get an error (see below)

actual error is in pear/HTTP/Request.php function _readChunked: $this->_chunkLength -= strlen($data);
With the slashes added, strlen(data) is larger than _chunkLength giving a negative value.

Reproduce code:
---------------
$Parser = &new HTTP_Request($file);
$Parser->sendRequest();
$xml_body = $Parser->getResponseBody();

quickfix for Request.php: (+/- line 1119)
---
$data = $this->_sock->read($this->_chunkLength);
$this->_chunkLength -= strlen($data);

//Added by Steven - 20050607
if ($this->_chunkLength < 0) $this->_chunkLength = 0;

if (0 == $this->_chunkLength) {
$this->_sock->readLine(); // Trailing CRLF
}

Expected result:
----------------
Valid XML structure

Actual result:
--------------
