Hello !

I am trying to write several counters for a program depending on some
types. I thus have written a template function containing a static int
which is increased each time the function is called. Across the
compilation units, the function should be instantiated only one for
each dependent type and the static variables be shared across
compilation units for each type. However under Visual C++ this is the
case when compiling in debug mode but not in release mode... Could
someone please tell me what should be the expected behavior ? and a
workaround ?

Thanks in advance,

Here is a simple test case :

// StaticInit.cpp
#include "Unit1.h"
#include "Unit2.h"

int main(int argc, char* argv[])
{
print1();
print2();
print1();
print2();
return 0;
}

// MyFunc.h
template <class T>
int myfunc(void)
{
static int i = -1;
return i++;
}

//Unit1.h
void print1();

//Unit2.h
void print2();

//Unit1.cpp
#include <iostream>
#include "Unit1.h"
#include "MyFunc.h"

void print1()
{
std::cout << "Print1 : " << myfunc }

//Unit2.cpp
#include #include "Unit2.h"
#include "MyFunc.h"

void print2()
{
std::cout << "Print2 : " << myfunc }

In debug mode, the result is as expected:
Print1 : -1
Print2 : 0
Print1 : 1
Print2 : 2

However in release mode, the result is :
Print1 : -1
Print2 : -1
Print1 : 0
Print2 : 0

Thanks in advance for your help,

Marc
