Using System.Reflection.Emit to emit code similar to:

  class Foo { 
   public Foo[] Foos;
  }

causes an assertion and runtime crash at mono_metadata_decode_row:

ERROR:metadata.c:965:mono_metadata_decode_row: assertion failed: (idx <
t->rows)
Stacktrace:



Reproducible: Always

Steps to Reproduce:
    [TestFixture]
    public class SreCircularArrayTypeTest
    {
        [Test]
        public void CircularArrayType()
        {
            var assemblyBuilder =
AppDomain.CurrentDomain.DefineDynamicAssembly(new AssemblyName("Test"),
AssemblyBuilderAccess.RunAndSave);
            var moduleBuilder = assemblyBuilder.DefineDynamicModule("Test",
"Test.dll", true);
            var typeBuilder = moduleBuilder.DefineType("Foo",
TypeAttributes.Public);
            var fieldBuilder = typeBuilder.DefineField("Foos",
typeBuilder.MakeArrayType(), FieldAttributes.Public);

            var fooType = typeBuilder.CreateType();
            Assert.AreSame(fooType.MakeArrayType(),
fooType.GetField("Foos").FieldType);
        }
    }
Actual Results:  
ERROR:metadata.c:965:mono_metadata_decode_row: assertion failed: (idx <
t->rows)
Stacktrace:


Expected Results:  
Test success.
