Hi,
I ran a few different numbers using gmp_gcdext on both 32 & 64 bit machines and most of the results are the same except the following example:


<?php

        $r = gmp_gcdext("34293864345", "23434293864345");
        var_dump(gmp_strval($r['g']));
        var_dump(gmp_strval($r['s']));
        var_dump(gmp_strval($r['t']));

echo "Done\n";
?>

On a 32 bit machine, the results are:
string(3) "195"
string(14) "-4760039754357"
string(10) "6965866288"
Done

On a 64 bit machine, the results are:
string(3) "195"
string(15) "-20983781660442"
string(11) "30707772373"
Done

Does anyone know why I have different results for "s" and "t" on 32 bit and 64 bit machines?

Thanks!
Waiki Wright
