I've been messing around with SSE in D.  One of the problems I've encountered is
forcing struct alignment to 16-byte boundaries in order to make use of movaps
and direct register-memory operations.  The problem with the align attribute is
that it only works on members within the struct.

In order to ensure alignment will I have to write a custom allocator, or am I
just using the attribute wrong?

I think the custom allocator is the way to go. To be honest I'm not sure you 
can write one for a struct but I suppose it's possible.
