+Summary: CS0165: local variable assignation placed after goto statement are incorrectly regarded as valid
+
+When we have goto statement inside a block and there is a local variable
+assignation after that goto, it must not be regarded as "already assigned"
+(since skipped execution might reference it). csc checkes it, but mcs does not.
+
+
+using System;
+
+public class Test
+{
+        public int i;
+
+        public void Hoge ()
+        {
+                if (i > 0)
+                        goto Fuga;
+                string s = "defined later";
+        Fuga:
+                Console.WriteLine (s);
+        }
+}
+
+Actual Results:
+compiled without CS0165 error.
+
+Expected Results:
+cs0165-goto.cs(13,22): error CS0165: Use of unassigned local variable 's'
+
+How often does this happen? 
+consistently.
