[Boost-users] [Boost-Threads] Assertion during a second call to thread::join()

Hi, Does anyone know the reason for the behavior in the following example program? This example attempts to simulate the scenario where two threads wait on a third thread. However, I realize that the following is actually one thread waiting on a second thread twice. Regards, Jason My Environment: MSVC 8.0, boost v1.33.1 #include #include void f() { } void main() { boost::thread t(f); t.join(); t.join(); // Causes an assertion }
