I have some problem with struct alignment. My struct is:
struct some_struct
{
    ubyte member1;
    ubyte member2;
    ubyte member3;
    ushort member5;
    ushort member6;
}
The appearance of members is fixed. member5 shifted by 1 byte down to member6. How to fix this problem?

align(1) struct some_struct { ... } will do the trick, I think.

As Russians say: The fakir was drunk, trick is not has gone right. :-(

Which compiler? Or have I misunderstood the question mayhaps, this program works under dmd 1.027:

struct some_struct
{
    ubyte member1;
    ubyte member2;
    ubyte member3;
    ushort member4;
    ushort member5;
}

align(1) struct some_struct2
{
    ubyte member1;
    ubyte member2;
    ubyte member3;
    ushort member4;
    ushort member5;
}

void main()
{
    assert(some_struct.sizeof == 8);
    assert(some_struct2.sizeof == 7);
}
