using System;

class Test  {
	static void Main ()
		Action a;
			for (int i = 0; i < 10; ++i) {
				a = delegate {
					Console.WriteLine (i);

			for (int i = 0; i < 10; ++i) {
				a = delegate {
					Console.WriteLine (i);

				if (i > 0) // Set a breakpoint here and on first hit hover over i (shows 10) or type 'i' in Watch window

I am also experiencing this bug.  A hover over pt in the screenshot will show the same values as the watch window.  The immediate window is also affected although he return value from the method shows correctly if called from the immediate window.

This is running in the iOS simulator.
