The ng_msghdr struct is 52 bytes / 4-byte aligned (see ng_message.h). That means the message payload is not well-aligned for 64-bit platforms. It would be nice to fix that (and bump NG_VERSION, of course). Nobody ever guaranteed that the message payload would be aligned, but it makes things a lot more convenient. John
