I complied against the latest cvs version and still got the leak.

   boost::thread_group::create_thread(boost::function0<void,
   std::allocator<boost::function_base> > const&) (thread.cpp:338)

It appears to come from this line in boost/lib/src/pthread.cpp:

   std::auto_ptr<thread> thrd(new thread(threadfunc));

Could it be that the leak is being created by using the tmp object in
the thread creation?  I've read advise about NOT doing that?

I realized after reading your email again that 1.34 is what you
specified, but I used 1.35.  Would that be a problem?

Thanks,

Pete
