+Summary: ListBox giving linked list corruption
+
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+Below is a small piece of code which uses a ListBox. It will compile and
+run fine, but when it exits, there is a report of a linked list corruption
+
+Steps to reproduce the problem:
+1. compile and run the application generated from the source
+2. 
+3. 
+
+Actual Results:
+There is a lot of backtrace (run it and see - sorry, I can't capture it)
+
+Expected Results:
+Should exit fine
+
+How often does this happen? 
+Always
+
+Additional Information:
+The source. Compile : mcs listbox.cs -r:System.Drawing -r:System.Windows.Form
+
+using System;
+using System.Drawing;
+using System.Windows.Forms;
+
+class ListBoxDemo : Form 
+{
+  ListBoxDemo()
+  {
+    ListBox lb = new ListBox();
+    for (int i = 0; i < 10; i++)
+      lb.Items.Add(i.ToString());
+    lb.Location = new Point (10, 10);
+    lb.SelectedValueChanged += new EventHandler(OnSelect);
+    Controls.Add(lb);
+  }
+
+  public void OnSelect(object src, EventArgs ea)
+  {
+    ListBox lb = (ListBox) src;
+    Console.WriteLine(lb.SelectedItem);
+  }
+
+  public static void Main()
+  {
+    Application.Run(new ListBoxDemo());
+  }
+}
