+Summary: [PATCH] ArgumentOutOfRangeException using TabControl.TabPages.Clear ()
+
+A recent regression in SWF causes the following exception when clearing the
+tab pages on a tab control:
+
+Unhandled Exception: System.ArgumentOutOfRangeException: ControlCollection
+does not have that many controls
+Parameter name: index
+-1
+in <0x0010a> System.Windows.Forms.Control+ControlCollection:get_Item (Int32
+index)
+in <0x00021> System.Windows.Forms.TabControl:GetTab (Int32 index)
+in (wrapper remoting-invoke-with-check)
+System.Windows.Forms.TabControl:GetTab (int)
+in <0x00013> System.Windows.Forms.TabControl+TabPageCollection:get_Item
+(Int32 index)
+in <0x000da> System.Windows.Forms.TabControl:set_SelectedIndex (Int32 value)
+in (wrapper remoting-invoke-with-check)
+System.Windows.Forms.TabControl:set_SelectedIndex (int)
+in <0x00129> System.Windows.Forms.TabControl+ControlCollection:Remove
+(System.Windows.Forms.Control value)
+in <0x000b0> System.Windows.Forms.Control+ControlCollection:RemoveAt (Int32
+index)
+in <0x00033> System.Windows.Forms.Control+ControlCollection:Clear ()
+in <0x0001a> System.Windows.Forms.TabControl+TabPageCollection:Clear ()
+in <0x00062> Test:Main ()
+
+To reproduce, compile and run the following code snippet:
+
+using System.Windows.Forms;
+
+public class Test {
+        static void Main() {
+                TabControl tab = new TabControl ();
+                tab.Controls.Add (new TabPage ());
+                tab.TabPages.Clear();
+        }
+}
+
+I'll attach a patch which fixes this issue, and adds a unit test for it.
