+Summary: Combination of #define and nested #if: missing #endif not detected
+
+Description of Problem:
+In a nested usage of #if, a missing #endif is not always detected 
+
+Steps to reproduce the problem:
+
+#define MYSYMBOL
+
+using System;
+
+namespace Test {
+
+public class Test {
+
+#if MYSYMBOL
+        public static int JustAFunction () { return 42; }
+#if NOTDEFINED
+        public static int JustAnotherFunction () { return 37; }
+#endif
+// An #endif is missing, a fact not detected by mcs
+
+        public static void Main ()
+        {
+                Console.WriteLine (JustAFunction ());
+        }
+}
+
+Actual Results:
+When the program above is compiled, no syntax error is given indicating the
+missing #endif. When the #define is removed, a syntax error IS given. 
+
+Expected Results:
+A syntax error like "#endif missing" 
+
+How often does this happen? 
+Always
