if you should get those 10 you have to add packed attribute to the struct
definition:

    struct TestStruct
    {
       struct
       {
          unsigned long Value1;
          unsigned long Value2;
          unsigned short Value3;
       } Value __attribute__ ((packed));
       unsigned long Value4;
    } Test __attribute__ ((packed));

otherwise the alignment will be always 4 bytes for any structure.
