The information in this article applies to:

- The C/C++ Compiler (CL.EXE), included with:
   - Microsoft Visual C++, 32-bit Enterprise Edition, version 4.2

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

SYMPTOMS
========

When defining a template function and a nontemplate function of the same name
such that the nontemplate version is defined within a namespace, you may
encounter the following error:

  

  test.cpp(28) : fatal error C1001: INTERNAL COMPILER ERROR
                 (compiler file 'msc1.cpp', line 1089)

RESOLUTION
==========

There are three ways to work around this problem:

1. Change the name of one of the functions involved.

-or-

2. Move the using directive to local function scope. See the sample code below.

-or-

3. Instead of a using directive, use the scope resolution operator to reference
  objects in the namespace. See the sample code below.

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article. This bug was corrected in Visual C++ version 5.0.
