boost::thread under Borland Turbo

Hi,

A specific problem arises when I try to use boost::thread 1.35.0 with
Borland Turbo 2006.
Code below compiles but when run it throws (in commented line - thread
creation):
"assertion failed: p_ != 0, file .\boost/intrusive_ptr.hpp, line 126"
(thread holds NULL pointer to thread function)
I've tested this code under gcc 3.4 (mingw32) and gcc 3.2 (linux) - it
worked fine in both cases.
Is there any workaround for this? I've tried googling and boost docs
but didn't find anything...

// file Server.h
//---------------------------------------------------

class Server {
  class ServerThread {
    public: ServerThread () { }
            ServerThread (const ServerThread &other) { }
            ~ServerThread () { }
            void operator() ();
  };

   public: Server () : serverThread (NULL) { }
           Server (const Server &other) : serverThread
(other.serverThread) { }
           ~Server () { }

           void StartServer (void);
           void StopServer (void);

   private: boost::thread *serverThread;
};

// file Server.cpp
//---------------------------------------------------

void Server::ServerThread::operator() ()
{
  while (1) { /* doing anything */ }
}

void Server::StartServer (void)
{
  if (!serverThread)
  {
// CRASHES HERE :
    serverThread = new boost::thread (Server::ServerThread (this));
  }
}

void Server::StopServer (void)
{
  if (serverThread)
  {
    serverThread->interrupt();
    delete serverThread;
    serverThread = NULL;
  }
}

// file main.cpp
//---------------------------------------------------
#include "Server.h"

int main (void)
{
  Server server;
  server.StartServer();
  server.StopServer();

  return 0;
}
