State-Changed-Why:
    Not a bug.  You are assuming that because your structure contains
    only char type elements that it will be only byte-aligned.
    This assumption is incorrect on the ARM, where structures are
    always word-aligned by default.
    
    You can fix the problem by adding __attribute__((packed)) at the end
    of your structure declaration.  See the manual for more details.
