Description:
------------
I added comments to bug #11939 but no reply (i might be doing something wrong) so opening up this case instead.

I tried the same tests as #11939 also (below for conveniance) and they still cause issues where Apache crashes.

Reproduce code:
---------------
$objHttp = new HttpRequest('http://www.google.com');
$objHttp->resetCookies();
// -> segmentation fault

// OR

$arrCookies = array('test' => 'testvalue');
$objHttp = new HttpRequest('http://www.google.com');
$objHttp->setCookies($arrCookies);
var_dump($objHttp->getCookies());
$objHttp->resetCookies();
// -> segmentation fault


Expected result:
----------------
Apache not to crash

Actual result:
--------------
Apache crashes, below are the results from both code examples.

First example produces the below.
szAppName : httpd.exe     szAppVer : 2.2.8.0     szModName : php_http.dll
szModVer : 5.2.6.6     offset : 0003ff45

Second example produces the below.
szAppName : httpd.exe     szAppVer : 2.2.8.0     szModName : php_http.dll
szModVer : 5.2.6.6     offset : 0003ff45

As stated in numerous other bug reports:

This is a problem of old libcurl installations.
It has been fixed upstream long time ago.
