Description of Problem:
There seems to be a problem related to array covariance and their support
of the ICollection<> interface.

Steps to reproduce the problem:
	class A
	{ }

	class B : A
	{ }

	class Program
	{
		static void Main(string[] args)
		{
			B[] array = new B[0];

			ICollection<A> collection = array;
			IEnumerator<A> enumerator = collection.GetEnumerator();
		}
	}

Actual Results:
System.NullReferenceException is thrown inside GetEnumerator. Sometimes
similar setups yield even this:

=================================================================
Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
=================================================================

Expected Results:
It should work. As it does in CLR.

How often does this happen? 
Always.
