 I have encountered another manifestation of this issue. I have produced a
 very simple test program that will exhibit the issue:



 {{{
 #include <boost/thread.hpp>
 #include <boost/shared_ptr.hpp>
 void GetThreadId(boost::shared_ptr<boost::thread::id> tidPtr)
 {
     *tidPtr = boost::this_thread::get_id();
 }
 int main(int argc, char* argv[])
 {
     for(;;)
     {
         boost::shared_ptr<boost::thread::id> tidPtr(new
 boost::thread::id());
         boost::thread thread(GetThreadId, tidPtr);
         tidPtr.reset(); // force necessity to pass tidPtr by value
         thread.join();
     }
     return 0;
 }

 }}}
 This program leaks memory every time around the for loop in main.
