+Summary: System.Reflection.Emit.TypeBuilder:CreateType crashes
+
+Description of Problem:
+
+I am using System.Reflection to create an assembly and I must be calling
+TypeBuilder::CreateType at the wrong time, but CreateType is crashing
+instead of telling me where the problem lies.
+
+CreateType can throw its own exceptions, but it should not propagate
+exceptions thrown by methods it called for itself.  Also, CreateType cannot
+throw NullReferenceExceptions:
+http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemreflectionemittypebuilderclasscreatetypetopic.asp
+
+
+Steps to reproduce the problem:
+
+I haven't isolated what in my code causes this exception.  Please let me
+know if it would help.  In TypeBuilder.CreateType, it's the line that says
+ "created = create_runtime_class (this);"
+
+
+Actual Results:
+
+Unhandled Exception: System.NullReferenceException: Object reference not
+set to an instance of an object
+in <0x00000> <unknown method>
+in (wrapper managed-to-native)
+System.Reflection.Emit.TypeBuilder:create_runtime_class
