+Summary: mcs incorrectly uses stelem.ref for pointer arrays.
+
+Consider the following program posted on the list:
+using System;
+
+namespace ConsoleApplication1 {
+   class Program {
+       static unsafe void Main(string[] args) {
+           int[] i = new int[] { 10 };
+           fixed (int* p = i) {
+               int*[] q = new int*[] { p };
+               *q[0] = 5;
+               Console.WriteLine(*q[0]);
+           }
+       }
+   }
+}
+
+mcs will emit stelem.ref to store into the array instead of stelem.i.
+The load is similarly broken: ldelem.ref instead of ldelem.i.
