 New Comment:

For some reason php_filter_parse_int multiplies the integer by ten then
attempts to eat a 0? This is causing overflow and resulting in an
error.

I have no idea why its doing this though. ilia?

Description:
------------
Although -2147483648 is the minimum integer in 32bit environment, 
FILTER_VALIDATE_INT says -2147483648 is invalid as integer.

Reproduce code:
---------------
<?php

var_dump(intval("-2147483648"));
var_dump(filter_var("-2147483648", FILTER_VALIDATE_INT));

Expected result:
----------------
int(-2147483648)
int(-2147483648)

Actual result:
--------------
int(-2147483648)
bool(false)
