Hello fellow boost fans,

Could anyone explain to me why the destructor (in the program listed below) seems to be called 10 times but the constructor only one time? The output of the program is also shown below.

I think that adding a copy constructor and/or an assignment operator to your sample will help with your enlightenment. ;-)

--- BEGIN PROGRAM --- #include #include <iostream>

using namespace std;

struct ThreadBug { ThreadBug() { cout << "Begin sending ... " << endl; }

~ThreadBug() { cout << "End sending ... " << endl; }

ThreadBug ( const ThreadBug &rhs ) { cout << "Copy constructing ... " << endl; } ThreadBug & operator = ( const ThreadBug &rhs ) { cout << "Assigning ... " << endl; return *this; }

void operator()() { cout << "Do something ... " << endl; } } w_ThreadBug;

int main() { cout << "New Sequence -----------" << endl; boost::thread thrd(w_ThreadBug); thrd.join(); cout << "End New Sequence -----------" << endl; return 0; } ---END PROGRAM ---
