+Summary: ArrayList.Insert(0, obj) causes endless loop
+
+The following code causes an endless loop in ArrayList. 
+
+The problem is in ArrayList.Shift: the internal array (_items) has length 
+0, thus the computation of the new length in a while loop (line 2820) with 
+length<<1 never ends.
+
+
+using System;
+using System.Collections;
+
+public class Test {
+
+
+    public static void Main(string[] args) {
+        ArrayList list = new ArrayList(new Object[0]);
+
+        list.Insert(0, "test");
+        Console.WriteLine("list-count:" + list.Count);
+    }
+
+
+}
