That's explains it then, I did cut down my code and the code following is
enough to have an hang:

Gaetano Mendola

#include <boost/thread.hpp>

struct Thread {
  Thread(boost::condition_variable& aCondition)
    : theCondition(aCondition), theMutex()
  { }

  void operator()() {
    boost::mutex::scoped_lock myGuard(theMutex);

  boost::condition_variable& theCondition;
  boost::mutex theMutex;

int main(int argc, char** argv) {

  boost::condition_variable myCondition;

  Thread myT1(myCondition);
  Thread myT2(myCondition);

  boost::thread_group myThreadGroup;
