+Summary: Mini regression.
+
+The following program fails to run on mini, it works on mono and on .NET
+1.0 and 1.1:
+
+// this tests making a pointer to a pointer
+
+using System;
+
+unsafe class Foo
+{
+        public static int Main ()
+        {
+                int a;
+                int *b;
+                int **c;
+
+                a = 42;
+                b = &a;
+                c = &b;
+
+                Console.WriteLine ("*c == b : {0}", *c == b);
+                Console.WriteLine ("**c == a : {0}", **c == a);
+
+                if (*c == b && **c == a)
+                {
+                        Console.WriteLine ("Test passed");
+                        return 0;
+                }
+                else
+                {
+                        Console.WriteLine ("Test failed");
+                        return 1;
+                }
+        }
+}
+
+It complains with:
