7772	Incorrect condition_variable::notify_one (win32 vc9)	jaime.legido@…	Anthony Williams	"When someone calls condition_variable::notify_one never ""generations.erase"" removes any element.

In versión 1.52 this code has been changed
thread\win32\condition_variable.hpp:196
struct entry_manager
{
...
                ~entry_manager()
                {
                  if(! entry->is_notified())
                  {
                    entry->remove_waiter();
                  }
                }
...

Never call ""entry->remove_waiter()"" therefore not remove anything from generations vector.



Code example

#define BOOST_THREAD_USE_DLL
#include <boost/thread.hpp>

boost::condition_variable cv;
boost::mutex mt;
void fTest()
{
	boost::mutex::scoped_lock sl(mt);
	while(1)
	{
		cv.wait(sl);
	}
}

int _tmain(int argc, _TCHAR* argv[])
{
	boost::thread th = boost::thread(boost::bind(&fTest));

	while(1)
	{
		cv.notify_one();
		boost::this_thread::sleep(boost::posix_time::seconds(1));
	}

	return 0;
