Description:
------------
We use a quite huge cookie lifetime in our application 
(b2evolution) which causes a segmentation fault with 
current CVS.

When I rename the cookie name and value, it 
becomes "zend_mm_heap corrupted" instead.

Reproduce code:
---------------
# "zend_mm_heap corrupted":
setcookie( 'foo', 'bar', 1487806696, '/blogs/', '.b2cvs18.local' );

# "Segmentation fault":
setcookie( 'cookieb2evosession', '33_9Bm6MWngjfF745MSCgoqREt3umW7ttC6', 1487806696, '/blogs/', '.b2cvs18.local' );


Expected result:
----------------
Nothing.

Actual result:
--------------
zend_mm_heap corrupted

or

Segmentation fault
