+Bug#: 76009
+Product: Mono: Compilers
+Version: unspecified
+OS: All
+OS Details: 
+Status: NEW   
+Priority: Wishlist
+Component: C#
+AssignedTo: rharinath at novell.com

+TargetMilestone: ---
+Summary: Using yield produces classes with duplicate field names.
+When using the new C# 20 keyword yield in an IEnumerable fields with 
+duplicate names are created within the auto-generated yield class if local 
+variables using the same name are defined in several places within the 
+It appears that the algorithm simply adds a field for every local variable 
+using the local variable name. If a name is used for a local variable more 
+then once then several fields using the same name will be created.
+Using the attached program, once compiled into a DLL you can see using 
+ildasm that '<ff>__' has two fields call 'i'. Trying to ilasm the code 
+generated by ildasm will fail.
