Hello,
here is a simplified code I wrote:

class A{
public:
     A();
     ~A();
     void Run();
     void ThreadA();
     virtual void HandleSomething();
};

void A::HandleSomething()
{

}

void A::ThreadA()
{
     if(condition)
     {
         HandleSomething();
     }
}

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.
