make sure that you join on the thread or else the thread object might be destructed before the thread having finished.

Subject: [Boost-users] Threads and virtual functions



      here is a simplified code I wrote:


      class A{




          void Run();

          void ThreadA();

          virtual void HandleSomething();



      void A::HandleSomething()





      void A::ThreadA()








      void A::Run()


          boost::thread thread(&A::ThreadA,this);



      This is my base class. As you can see the thread calls the virtual
      function when the condition becomes true. I use the virtual
      function in my derived class so everytime the condition becomes
      true the function HandleSomething() should do something. So far,
      so good but when I try to change some variables in the derived
      class the program crashes without any warning or error message. I
      use the latest Ubuntu version with GCC 4.5.3 and boost 1.46.1.
