PR# 15708 Incorrect VUOT error being reported in debugger watch window

I was trying to  evaluate the value of `l_name' which is a true local variable of that routine. In this routine, I'm using  twice `l_library' as an object test local and the debugger  is confused about that as you can see in the error  below reported by the debugger watch window.

Error on expression : "l_name"
[VUOT] Error VUOT
Error code: VUOT(1)

Error: Object-Test Local has the same lower name as a feature of the
  enclosing class, or a formal argument or local variable of an enclosing
  feature or Inline_agent, or other Object-Test Local with the scope where
  this Object_test or its scope appears.
What to do: choose a different name for Object-Test Local.

Class: EB_COMPARE_LIBRARY_CLASSES_TOOL
Feature: compare_libraries
Object-Test Local: l_library
Line: 234
          end
->        if attached {CONF_LIBRARY} l_cluster2 as l_library and then l_library.name_prefix /= Void then
            create l_new_classes.make (l_classes2.count)
