+Summary: Crash when compiling IronPython 2.0 Alpha 3
+
+The new clone functionality introduced a new crash.
+
+Steps to reproduce:

+
+http://www.codeplex.com/IronPython/Release/ProjectReleases.aspx?ReleaseId=3749
+
+2. Unpack and go into the Src directory
+
+3. Run this command:
+gmcs -t:library -t:library -out:../Bin/Debug/Microsoft.Scripting.dll
+-r:System.Configuration.dll -recurse:Microsoft.Scripting/*.cs
+
+This results in:
+
+Unhandled Exception: Mono.CSharp.InternalErrorException:
+Microsoft.Scripting/ReflectedTypeBuilder.cs(367,17): --->
