+Summary: Unable to cast a ulong to a IntPtr
+
+Description of Problem:
+
+
+Steps to reproduce the problem:
+1.  Create a .cs that contains:
+
+using System;
+
+namespace MicroFocus.MONO.Bugs
+{
+       public class IntPtrTest
+       {
+               public static uint MyVirtualAddress32()
+               {
+                       return (uint)2147483647;
+               }
+
+               public static ulong MyVirtualAddress64()
+               {
+                       return (ulong)9223372036854775807;
+               }
+
+               public static int Main()
+               {
+                       IntPtr x = IntPtr.Zero;
+
+                       if (IntPtr.Size == 4)
+                               x = (IntPtr)MyVirtualAddress32();
+                       else
+                               x = (IntPtr)MyVirtualAddress64();
+
+                       if (x != IntPtr.Zero)
+                       {
+                               Console.WriteLine("PASS");
+                       }
+                       else
+                       {
+                               Console.WriteLine("FAIL");
+                       }
+                       return 0;
+               }
+       }
+}
+
+2. gmcs the above
+
+Actual Results:
+D:\development\netx50\ilrts\mono\bugs>call gmcs IntPtrTest1.cs
+IntPtrTest1.cs(24,10): error CS0030: Cannot convert type `ulong' to 
+`System.IntP
+tr'
+
+
+Expected Results:
+
+D:\development\netx50\ilrts\mono\bugs>csc IntPtrTest1.cs
+Microsoft (R) Visual C# 2005 Compiler version 8.00.50727.42
+for Microsoft (R) Windows (R) 2005 Framework version 2.0.50727
+Copyright (C) Microsoft Corporation 2001-2005. All rights reserved.
+
+
+D:\development\netx50\ilrts\mono\bugs>IntPtrTest1
+PASS
+
+How often does this happen? 
+
+Everytime we cast a ulong to a IntPtr
+
+Additional Information:
+
+The code snippet is from our COBOL compiler's Runtime... Our Runtime
+runs on both 32bit and 64bit, and as such is sensitive to the IntPtr.Size.
+
+Please note, the IntPtr does *NOT* contain a unmanaged physical address
+but contains a value in our own virtual address map.
+
+If you have any questions, please feel free to drop me a line.
