Yes, it's copied and you're not logging construction in your copy constructor. It's working as designed.

I think boost makes a copy of the object (i'm sure someone else will confirm/shoot this down), though I'm not sure if it would cause that. try passing a boost::ref?

Recently, I download boost 1.31.0 and compile it with Visual studio.net 2003. But the code below can't work properly:
class A { public: A() { printf("constructor.\n"); }
~A() { printf("destructor.\n"); }
void operator () () { } };
int main(int argc, char* argv[]) { A a; boost::thread t(a); t.join(); }
In my system, it generate the message like this: D:\thread\Debug>thread.exe constructor. destructor. destructor. destructor. destructor. destructor. destructor.
Who can tell me what's wrong with boost or something else?
