+Summary: Iterators generated local access to captured caught variables.
+
+The following program should display OK:
+
+using System;
+using System.Collections;
+
+class XX {
+	static void Metodo (Exception e)
+	{
+		if (e is NotImplementedException){
+			Console.WriteLine ("OK");
+		} else {
+			Console.WriteLine ("Fail");
+		}
+	}
+	
+	static IEnumerable X ()
+	{
+		try {
+			throw new NotImplementedException ();
+		} catch (Exception e){
+			Metodo (e);
+		}
+		yield return 0;
+	}
+	
+	static void Main ()
+	{
+		foreach (int a in X ()){
+		}
+	}
+}
+
+The problem is that the code generated for storing the Exception in the
+catch is:
+
+            catch [mscorlib]System.Exception { // 0
+              IL_0010:  stloc.1 
+              IL_0011:  ldarg.0
+              IL_0012:  ldfld  class [mscorlib]System.Exception XX/'<X>__0'::e
+              IL_0017:  call void class XX::Metodo(class
+[mscorlib]System.Exception)
+              IL_001c:  leave IL_0022
+    
+            } // end handler 0
+
+The `stloc' there is hardcoded somehwere, but it should store the data into
+the XX/<X>__0::e field instead of the local
