+This does not compile with csc. It says:
+bug36055.cs(12,32): error CS0212: You can only take the address of
+unfixed expression inside of a fixed
+        statement initializer
+The right code in Main should be (it compiles with mcs):
+             CData d=new CData();
+             fixed (int *p=&d.x) *p=3;
+             Console.WriteLine ("{0}", d.x);
