This example produces the following code for me:

  %4 = load [2 x i32]*, [2 x i32]** %1, align 8
  %arrayidx = getelementptr inbounds [2 x i32], [2 x i32]* %4, i64 0, i64 0
  store i32* %arrayidx, i32** %3, align 8
  br label %init.end

This is successfully interpreted via IRInterpreter with the current patch (i.e. all arguments seem to be `ConstantInt`).
