The issue is casting a ref T[] to a ref const(T)[].

The safety is broken if you implicitly apply const two references deep.

I think this is a dup of bug 2095 (which actually is dup of a sub-1000 bug). 
But I think the const implications are somewhat new.  I recall there was either
a discussion on the NG or another bug that covers this.  Maybe someone else can
find it.
