Description:
------------

I have used the code from the test script on my development machine (Windows Professional 7 32bit) with php 5.2.12 and is working correctly but when I have deployed on my production machine that is FreeBSD 6.3 32bit with the same php version 5.2.12 is giving wrong results (-2147483593). I also run this on other production machine that is RedHat 5 32bit with php 5.2.6 and is also giving wrong results (-2147483593).

I can not test with php 5.2.13 on production machines (virtual hosting).
On windows is giving the correctly result (754303898) with PHP 5.2.12 and PHP 5.3.1. I am running in 32bit platform on all machines.
