+Summary: SIGSEGV loading enum with no value__ field
+
+When an enum containing no value__ field is loaded, a TypeLoadException 
+should be thrown. However, on Mono this results in a SIGSEGV.
+
+To reproduce:
+1. compile the attached IL (using ilasm /exe test.il)
+2. run the assembly.
+
+Expected result:
+
+Unhandled Exception: System.TypeLoadException: No Instance Field in an 
+Enum. (MS .NET 2.0)
+-or-
+Unhandled Exception: System.TypeLoadException: Could not load type 
+FieldAttributes from assembly test, Version=0.0.0.0, Culture=neutral, 
+PublicKeyToken=null. (MS.NET 1.1)
+
+Actual result:
