FIX: C1001, file 'msc1.cpp', line 1188, Caused by Name Hiding

• Microsoft Visual C++, 32-bit Editions, version 5.0

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.
