+Summary: the last branch of "for" statement is incorrectly skipped
+
+This looks like a bug in computation of unreachable block in "for"
+statement. The example below results different when compiled with csc and
+when compied with mcs:
+
+--------
+using System;
+
+public class Test
+{
+        static int flag = 0;
+        static int iter = 1;
+
+        public static void Main ()
+        {
+                for (int x = 0; x <= iter; x++, iter--) {
+                        if (flag == 0)
+                                continue; // iter
+                        else
+                                break;
+                }
+                Console.WriteLine (iter);
+        }
+}
+
+Steps to reproduce the problem:
+1. compile with mcs and run
+2. compile with csc and run (don't worry; I put the result below)
+
+
+Actual Results:
+$ mcs forloop.cs
+forloop.cs(10) warning CS0162: Unreachable code detected
+ - 1 warning(s)
+
+$ mono forloop.exe
+1
+
+Expected Results:
+$ csc /nologo forloop.cs
+
+$ mono forloop.exe
+0
+
+How often does this happen? 
+- Consistently.
