+Summary: IronPython and System.Reflection.Emit problem
+
+SVN revision 60112. Always reproducible.
+
+1. Get IronPython 1.0 Beta 6.
+
+2. Create test.py
+
+class C:
+    pass
+
+3. Run as
+mono IronPythonConsole.exe -X:GenerateAsSnippets test.py
+
+4. Expected result is no error. This works fine with MS.NET.
+
+5. Run as
+mono IronPythonConsole.exe -X:ExceptionDetail -X:GenerateAsSnippets test.py
+
+This produces more useful output:
+
