-------------------------------------------------------------------------------
The information in this article applies to:

- The C/C++ Compiler (CL.EXE), used with:
   - Microsoft Visual C++, 32-bit Enterprise Edition, version 5.0sp3 
   - Microsoft Visual C++, 32-bit Professional Edition, version 5.0sp3 
   - Microsoft Visual Studio 97sp3 
-------------------------------------------------------------------------------

SYMPTOMS
========

If you are using a third-party Standard Template Library (STL) (such as the
Hewlett-Packard implementation), and compile after applying Visual Studio 97
Service Pack 3, the following error may be generated:

  testerr.cpp bstring.h(2322) : fatal error C1001: INTERNAL COMPILER ERROR
  (compiler file 'E:\utc\src\\P2\main.c', line 379)
  Please choose the Technical Support command on the Visual C++ Help menu, or
  open the Technical Support help file for more Information.

RESOLUTION
==========

The following are suggested workarounds:

- Separate the construction and return of a temporary object. In the example
  below, replace the return statement with the respective commented
  statements:

         if (length())
        {
             return basic_string<charT>(data()+pos, (n > (length()-pos)) ?
                    (length()-pos) : n);

             //basic_string<charT> bt(data()+pos, (n > (length()-pos)) ?
             //     (length()-pos) : n);
             //return bt;
        }
         else
        {
         return basic_string<charT>();// C1001 on this line
             // basic_string<charT> bt;
             // return bt;
        }
     }

- Use Visual Studio 97 SP2.

- Instead of using the Hewlett-Packard STL, use the STL provided in Visual C++
  5.0. See any STL sample in the Visual C++ Online documentation for usage
  information. You may also read the comprehensive information provided on the
  Web at: http://www.microsoft.com/visualc/stl.

STATUS
======
