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);
foreach(initializerSegment;StructType.InitializerSegments)
{
memcpy((cast(void*)structPtr) +
initializerSegment.segmentOffset,
(cast(void*) initializerSegment.segmentPtr),
initializerSegment.segmentSize);
}

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.
