Description:
------------
Reusing a cURL request while using CURLOPT_RETURNTRANSFER=true causes
the result of the first curl_exec() to still be in the body of the
second curl_exec().  Possibly, buffer isnt being cleared.

I cant explain it properly, but the example code below should be able
to.

This only happens on 4.4.6, and not on 4.4.4

Workaround is to use ob_start(); curl_exec($ch); $data=ob_get_clean();

Reproduce code:
---------------
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);


curl_setopt($ch, CURLOPT_URL, 'www.myjobspace.co.nz');
$data1 = curl_exec($ch);

curl_setopt($ch, CURLOPT_URL, 'www.myjobspace.co.nz/search');
$data2 = curl_exec($ch);


if (strpos($data2, $data1)===0)
{
	echo 'cURL Buffer is NOT being cleared';
} else {
	echo 'Everything ok';
}

Expected result:
----------------
Everything ok

Actual result:
--------------
cURL Buffer is NOT being cleared
