Bug description: big integers don't overflow
Description:
------------
If big number (2500072158) is converted to integer, php 5.0.2 does not
overflow and uses max integer value (2147483647).
OS details: Linux Debian Sarge
PHP compilation details (vanilla php-5.0.2.tar.bz2):
./configure --disable-debug --with-apxs=/somepath/apache/bin/apxs
--prefix=/somepath/php
--with-config-file-path=/somepath/
--with-pcre-regex --enable-mbstring --enable-session --disable-all
--with-gettext=shared,/usr
php.ini details:
error_reporting=E_ALL
display_errors=on
register_globals=off
asp_tags=on
short_tags=off
Is this standard future php behaviour or just some error in my config?
Reproduce code:
---------------
echo (int)0xde120495;
Expected result:
----------------
-569244523
Actual result:
--------------
2147483647
