10237	[windows] condition_variable wait infinitly	anonymous	viboes	"Os:any windows


The app will wait infinitly when app code like below:


//thread A
{{{
cout<<""Start to wait B...""<<endl;
con.wait(lock);
cout<<""Run A...""<<endl;
boost::this_thread::sleep(boost::posix_time::seconds(1));//do something
cout<<""Start to notify B...""<<endl;
con.notify_one();
cout<<""End to notify B...""<<endl;
}}}

//thread B
{{{
boost::this_thread::sleep(boost::posix_time::seconds(2));//do something
con.notify_one();
boost::this_thread::sleep(boost::posix_time::seconds(2));
cout<<""Start to wait A...""<<endl;
con.wait(lock);//thread A will call notify_one before this line
cout<<""Run again A...""<<endl;
}}}

cause:\boost\thread\win32\condition_variable.hpp line 261
{{{
if(detail::interlocked_read_acquire(&total_count))
}}}
The code will get read acquire count,and skip release when read acquire count is zero"	Bugs	closed		thread	Boost 1.55.0	Problem	invalid	condition_variable wait
