+Summary: Iterator compiles to invalid IL
+
+Please fill in this template when reporting a bug, unless you know what 
+you are doing. 
+Description of Problem: 
+ 
+ 
+Steps to reproduce the problem: 
+ 
+1. Create test.cs: 
+ 
+//test.cs starts 
+using System.Collections; 
+ 
+public class Test { 
+	public static void Main (string[] args) 
+	{ 
+		foreach (object o in Iterate ()) 
+			/*do nothing*/; 
+	} 
+ 
+	static IEnumerable Iterate () 
+	{ 
+		while (true) { 
+			if (Condition) 
+				break; 
+		} 
+ 
+		yield break;	//yield return fails in the same way 
+	} 
+ 
+	static bool Condition { 
+		get { return true; } 
+	} 
+} 
+//test.cs ends 
+ 
+2. Compile test.cs: 
+ 
+mcs /2 test.cs 
+ 
+(the /2 is not necessary, though I think it should be) 
+ 
+3. Run test.exe 
+ 
+mono test.exe 
+ 
+Actual Results: 
+ 
+** ERROR **: Invalid IL code at IL002d in 
+__Proxy_0:System.IEnumerator.MoveNext (): IL_002d: ret 
+ 
+Expected Results: 
+ 
+(program runs and finishes without outputing anything) 
+ 
+How often does this happen?  
+ 
+every time
