+Summary: Enum casting problem
+
+Description of Problem:
+There is a problem when using an enum as the target or the source for 
+casting, sometimes can't convert and others a crash is produced depending 
+on the other type involved in the casting.
+
+Additional Information:
+Using snapshot of Feb-25-02.
+
+Source code to reproduce the problem:
+namespace N1
+{	
+	public enum A
+	{
+		A_1, A_2, A_3
+	}
+
+	public class B
+	{
+		void ShortCasting ()
+		{
+			short i = 0;
+			N1.A a = N1.A.A_1;
+
+			i = (short) a;	//<- crash
+			a = (N1.A)i;//<- fails, can't convert
+		}
+
+		void IntCasting ()
+		{
+			int i = 0;
+			N1.A a = N1.A.A_1;
+
+			i = (int) a;//<- works fine
+			a = (N1.A)i;//<- fails, can't convert
+		}
+	}
+}
