-------------------------------------------------------------------------------

SYMPTOMS
========

Name hiding caused by similar-named variables and user-defined types in the same
scope may cause the compiler to generate the following error:

  C1001: INTERNAL COMPILER ERROR
  (compiler file 'msc1.cpp', line 1188)

RESOLUTION
==========

Use the elaborated type specifier to name the user-defined type. For example,
use "class a::b" instead of "b" to identify the class b nested in class a.

STATUS
======

beginning of this article. This bug has been fixed in Visual Studio 97 Service
