Description:
------------
I found this problem with respect to PHP 5.3.3 (which is not in the "PHP version" list) on amd64 architecture. On the x86 one, it works.

pecl_http from at least 1.6.6 reproducibly crashes executing the "reproduce code" below.

Reproduce code:
---------------
<?php
$req = new HttpRequest('http://127.0.0.1/index.html');
$req->setHeaders(array('Host' => 'www.example.com'));
$http =& $req->send();
echo($http->getResponseCode());
?>


Expected result:
----------------
302 or 404, depending on your web server config

Actual result:
--------------
Segmentation fault

Please note the problem seems related bug#15499 . In fact, I solved it by applying a similar patch:

Thank you for taking the time to report a problem with the package.
Unfortunately you are not using a current version of the package -- 
the problem might already be fixed. Please download a new
version from http://pecl.php.net/packages.php

If you are able to reproduce the bug with one of the latest
versions, please change the package version on this bug report
to the version you tested and change the status back to "Open".
Again, thank you for your continued support of PECL.

Cannot reproduce.
