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

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. _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users
