During the s initialization, the entire "S" area is initialized, including the member arr which we asked to be = void.

Is this a bug?

So currently on initalizsation we do this:
structPtr = cast(StructType*) alloc(structSize);
memcpy(structPtr, StructType.static_struct_initializer, StructType.sizeof);
which we could change to
structPtr = cast(StructType*) alloc(structSize);
memcpy((cast(void*)structPtr) + initializerSegment.segmentOffset,
           (cast(void*) initializerSegment.segmentPtr),

This will potentially remove quite a lot of binary bloat since void-members do no longer need to be stored in initializers, and initialization overhead. In terms of implementation this _should_ be straight-forward but well ... runtime and compiler interaction can be a mess.
