SYMPTOMS
========
When specializing a member function that is defined inside the class template,
the specialized member function never gets called although there is no compiler
error or linker error reported.
RESOLUTION
==========
Do not define the member function in the class template. See the Sample Code
below for an example.
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.

Sample Code to Reproduce Problem
--------------------------------
/* Compile options needed: Default
*/
# include <iostream.h>
template<class T>
struct TempStruct
{
void bar() { cout << "Template generated" << endl; }
// Change the previous line into a comment and execute the following
// line to work around the problem:
// void bar();
};
// Execute the following lines to work around the problem:
// template <class T>
// inline void TempStruct<T>::bar()
// {
// cout << "Template generated" << endl;
// }
void TempStruct<float>::bar()
{
cout << "Template specialized" << endl;
}
void main()
{
TempStruct<int> F1;
TempStruct<float> F2;
F1.bar();
F2.bar();
}
// The output from the program is:
Template generated
Template generated
// The output should be:
Template generated
Template specialized
