7464,BOOST_TEST(n_alive == 1); fails due to race condition in a regression test tool,greg.nowakowski@…,viboes,"This problem is at least from boost_1_50_0
Using gcc-4.1.2, but it has nothing to do with the bug.
Platform Linux.

All libs/thread/test modules that test n_avail are having race condition which make cause regression test to fail here :

{{{
  void operator()()
  {
    BOOST_TEST(alive_ == 1);
    BOOST_TEST(n_alive == 1); // race condition error
    op_run = true;
  }
}}}

Rationale:

When the G() object is being passed, copy constructor is used to copy the object. Then boost::detail::thread_data<G>::run() is executed and G::operator()() called.
If this operator is called before the main thread calls ~G(), n_avail may be 2. It is a very rare case to have the new thread execute operator()() before the main thread, and that is why it is so difficult to catch it.

Blessings,
Greg.
