commit 468f30e4abee27a5d55bcd211bf6deea66f3fb36

    Fix build on x86_64
    
    A pointer does not equal to an int on x86_64
    (which results into pointer - pointer not being an int either),
    fix that by casting the resulting value  to an int.
    
    Breakage was introduced by commit 909b5ec43c6f5ce2f97c5860b983610ae3d6d053
