+Summary: DivideByZeroException thrown in uint division when NOT dividing by zero.
+
+Description of Problem:
+In some cases, uint division throws a DivideByZeroException
+when the high bit of the dividend is set but the divisor is not zero.
+
+
+Steps to reproduce the problem:
+Compile and run this:
+
+using System;
+
+public class MonoDivideProblem
+{
+        static uint  dividend = 0x80000000;
+        static uint divisor = 1;
+        public static void Main(string[] args)
+        {
+                Console.WriteLine("Dividend/Divisor = {0}", dividend/divisor);
+        }
+
+}
+
+Actual Results:
+
+$ ./MonoDivideProblem.exe
+
+Unhandled Exception: System.DivideByZeroException: Division by zero
+in <0x0002d> MonoDivideProblem:Main (System.String[] args)
+$
+
+Expected Results:
+
+It should have printed 
+  Dividend/Divisor = 2147483648
+like it does when compiled with 
+csc (Compiler version 7.10.6001.4, framework 1.1.4322) on Windows.
+
+
+How often does this happen? 
+
+Every single time.
+
+Additional Information:
+
+The patterns we notice are:
+  -- division is a uint divided by a uint
+  -- the high bit is set in the dividend   (e.g. 0x80000000)
