Re: [Boost-users] [boost.thread] destruction of condition variables

Anthony Williams:

However, it is never safe to destroy any object whilst another thread might still be in a member function.

I believe that this is a "POSIX destruction safety" issue. POSIX CVs are supposed to support such code.

If you use your mutex to protect the notify too, everything will be fine.

I think that if the mutex doesn't offer "POSIX destruction safety", the code can still fail. Thread A may be unblocked and destroy the mutex while thread B is still in mutex::unlock. http://lists.boost.org/Archives/boost/2004/07/68477.php
