Yes, it's using a size_t which AFAIK is limited to 32bit on most
systems.

Description:
------------
Looks like memory_limit is kept using a 32-bit signed integer even with
php compiled on 64-bit Linux.

Reproduce code:
---------------
set memory_limit to -1 or >= 2048M

<?= count(file("a_big_file")) ?>

Expected result:
----------------
number of lines in "a_big_file".

Actual result:
--------------
"Integer overflow in memory_limit check detected"
