SYMPTOMS
========

Compiling code with a default argument for a string parameter in a function
declaration results in the following:

  Test.cpp() : fatal error C1001: INTERNAL COMPILER ERROR
               (compiler file 'msc1.cpp', line 1188)
      Please choose the Technical Support command on the Visual C++
      Help menu, or open the Technical Support help file for more information

CAUSE
=====

This bug was introduced in Visual Studio 97 Service Pack 3. It was not in
earlier versions of Visual C++ 5.0.

RESOLUTION
==========

Either upgrade to Visual C++ 6.0, or define a string in the file before the
function declaration.

STATUS
======

Microsoft has confirmed this to be a problem in the Microsoft products that are
listed at the beginning of this article.

This bug was corrected in Microsoft Visual C++, version 6.0.

MORE INFORMATION
================

The following sample code demonstrates the problem and the workaround:

  #include <string>
  using namespace std ;

  // Uncomment the following line to work around the problem
  //static std::string empty = ""; 

  void test( string sname = "" );

  void main()
  {
     test( ) ;
  }

Note that the empty string declaration must be in the same translation unit as
the function declaration.
