What is special about this specific struct that it needs such an
alignment?

I guess what I'm asking is why did GCC emit the movaps instruction for
assigning a value to a struct member in this case?  To do that, GCC
must have decided that this particular struct should be 16-byte
aligned, but what was the rationale for such a decision?

Thanks.
