I get two different results in doing a Xor on a large signed double
between linux servers.
working system is kernel 2.4 . bad results server is kernel 2.6.

PHP version does not matter. I compile PHP from 4.2.2 to latest.

test code:
<?PHP echo -4738698913 ^ 43814; ?>

results:

Good result from 2.4 kernel system is -443704711
Bad result from 2.6 kernel systems(tried 5 different systems) is
-2147439834

BUG in PHP or kernel?
