--- Comment #13 from Murat Ursavaş <murat.ursavas at gmail dot com> --- Richard, Also as far as I remember GNU manual was indeed saying something on this case. It was saying that "if the struct is not packed, it would access to members word by word. But if unaligned access is disabled, it would access the variables byte by byte and create longer and slower images. With unaligned access, it should access to the struct members again word by word." I can't show where it's written but I remember it. With the direct access, it is indeed accessing word by word no matter -pack-struct option is. But if I access it indirectly with a pointer, it tries to access byte by byte and still can't assign the values developer want.
