This is on 32 bit Linux. I'm not sure whether % is supposed to work
with numbers bigger than LONG_MAX.
No problem with long2ip here.

I don't see any problem here, the script below produce the correct
output:
[derick@kossu derick]$ php-4.3.2RC4
<?php
echo long2ip(3232238081);
?>
192.168.10.1
Please submit a valid script that reproduces this problem.

long2ip(3232238081) = '192.168.10.-255'
3232238081 % 256 = -255
must be:
3232238081 % 256 = 1
