Description:
------------
If cookie value is NULL, http_build_cookies() tries to 
allocate too much memory 
for some reason.

HTTP extension version is 1.6.6. I can reproduce this with 
PHP versions 5.2.8 and 
5.3.1 on Ubuntu, but not in 5.2.12 on FreeBSD.

Passing cookie value through strval() helps.

Reproduce code:
---------------
var_dump(http_build_cookie(array(
  'cookies' => array(
    'empty' => null,
    ),
)));

Expected result:
----------------
$ php -f test-cookies.php 
string(8) "empty=; "

Actual result:
--------------
$ php -f test-cookies.php 

Fatal error: Allowed memory size of 33554432 bytes exhausted 
(tried to allocate 
441559261 bytes) in .../test-cookies.php on line 7

This bug has been fixed in SVN.

In case this was a documentation problem, the fix will show up at the
end of next Sunday (CET) on pecl.php.net.

In case this was a pecl.php.net website problem, the change will show
up on the website in short time.
 
Thank you for the report, and for helping us make PECL better.
