Ticket 49424 - Resolve csiphash alignment issues
    
    Bug Description:  On some platforms, uint64_t is not the same size
    as a void * - as well, if the input is not aligned correctly, then
    a number of nasty crashes can result
    
    Fix Description:  Instead of relying on alignment to be correct,
    we should memcpy the data to inputs instead.
