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

- Microsoft Visual C++, 32-bit Editions, versions 2.0, 2.1 
-------------------------------------------------------------------------------

SYMPTOMS
========

When initializing a static data member that has a user-defined type in a class
template, the compiler generates the following error message on the line after
the last line of code:

  Error C2143: syntax error : missing ';' before 'newline'

RESOLUTION
==========

To work around the problem, specify a specialized instance for particular data
types when initializing the static data member -- as in the "Sample Code"
section in this article.

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article. This problem was corrected in Microsoft Visual C++,
32-bit Edition, version 4.0.

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

The following code can be used to reproduce the problem and work around the
problem.

Sample Code
-----------

  /* Compile options needed: /c
  */ 

  typedef struct
  {
    int element;
  } MyType;

  template <class T1>
  class AA
  {
    public:
      static MyType m_mytype;
  };

  template <class T1> MyType AA<T1>::m_mytype = {0};

  // Uncomment the following line to work around the problem.
  // MyType AA<double>::m_mytype = {0};

  AA<double> mydouble;

  MyType mytype = mydouble.m_mytype;
