This simple code causes memory leak on Mono 2.x

gistfile1.cs

using System;

namespace MemoryLeakTest
{
  class MainClass
	{
		public static void Main (string[] args)
		{
			for (;;) {
				var testArray = new TestStruct[500 * 500 * 50];
				var totalMemory = GC.GetTotalMemory(false);
				Console.WriteLine("total mem = {0}MB", totalMemory / 1024 / 1024);

				GC.Collect();
				System.Threading.Thread.Sleep(1000);
			}
		}
	}

	struct TestStruct
	{
		public int field1;
		public int field2;
		public int field3;
		public int field4;
		public int field5;
	}
}
