+Summary: mcs crashes when compiling separate "corlib" type
+
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+
+mcs and gmcs crash when trying to compile a file that has a type with the
+same name as a builtin.
+
+Steps to reproduce the problem:
+1. Compile the following code:
+
+	namespace System {
+		public struct Int32 {
+		}
+	}
+
+Actual Results:
+
+Unhandled Exception: System.NullReferenceException: Object reference not
+set to an instance of an object

+
+
+Expected Results:
+
+No crash, and (preferably) the creation of an assembly with the type
+System.Int32.
+
+How often does this happen? 
+
+Always.
