The thread local storage leaks memory on Windows/MSVC6.

Is this a know issue?

Small example (the tss.cpp example amended by leak debugging functions):

#define _CRTDBG_MAP_ALLOC
#include <stdlib.h> 
#include <crtdbg.h> 


#include <boost/thread/thread.hpp> 
#include <boost/thread/tss.hpp> 
#include <cassert> 

boost::thread_specific_ptr<int>  value;

void increment()
{
    int* p = value.get();
    ++*p;
}

void thread_proc()
{
    value.reset(new int(0)); // initialize the thread's storage
    for (int i=0; i<10; ++i)
    {
        increment();
        int* p = value.get();
        assert(*p == i+1);
    }
}

int main(int argc, char* argv[])
{
	_CrtDumpMemoryLeaks();

    boost::thread_group threads;
    for (int i=0; i<5; ++i)
        threads.create_thread(&thread_proc);
    threads.join_all();
}

Debug output window:
