+Summary: Finalizers not called anymore after an unhandled type load exception in a finalizer
+
+Finalizers not called anymore after an unhandled type load exception in a
+finalizer. It can be reproduced with the following test app:
+
+
+using System;
+
+public class Test
+{
+	public static void Main ()
+	{
+		while (true) {
+			for (int n=0; n<10000; n++)
+				new WithFinalizer ();
+
+			Console.WriteLine ("Live objects: " + WithFinalizer.ccount);
+			Console.ReadLine ();
+		}
+	}
+}
+
+class WithFinalizer
+{
+	public static int ccount;
+	public static bool crash = true;
+	
+	public WithFinalizer ()
+	{
+		ccount++;
+	}
+	
+	~WithFinalizer ()
+	{
+		ccount--;
+		if (crash && ccount == 5000) {
+			Console.WriteLine ("Crashing");
+			crash = false;
+			new Crasher ();
+		}
+	}
+}
+
+class Crasher
+{
+	static Crasher ()
+	{
+		throw new Exception ();
+	}
+	
+	~Crasher ()
+	{
+	}
+}	
+
+The application creates sets of 10000 instance of WithFinalizer objects at
+every Enter press. However, in the first run it will crash in a finalizer.
+The crash happens when trying to create an instance of Crasher, which
+throws an exception in the class constructor. After this crash, finalizers
+are not called anymore.
+
+Notice that if the exception shown is a regular exception it does not
+happen. It also does not happen if the Crasher class does not have a finalizer.
