ROOT CAUSE: The glue layer is misinterpreting it as an array block assignment,
so for a 5 element array, it duplicates the array five times. It recognizes
that strings are slice assignments rather than block assignments, but it needs
to do the same thing for array literals.


PATCH(against DMD2 svn 382): todt.c, line 1001 in TypeSArray::toDtElem.


    }
-    else if (e->op != TOKstring)
+    else if (e->op != TOKstring && e->op != TOKarrayliteral)
    {   // Array block assignment (rather than slice assignment)
        for (i = 1; i < len; i++)
        {
        if (tbn->ty == Tstruct)
        {   pdt = tnext->toDt(pdt);
            while (*pdt)
            pdt = &((*pdt)->DTnext);
        }
        else
            pdt = e->toDt(pdt);
        }
    }
