c – boost :: interprocess :: scoped_lock应用程序在锁内部崩

这打算如何工作？
我举一个下面代码的简单例子.

{
    boost::interprocess::named_mutex lockMutex(boost::interprocess::open_or_create,"lockName");
    boost::interprocess::scoped_lock<boost::interprocess::named_mutex> lock(lockMutex);
    //crash here
}

我最终做了一个像下面这样的超时.谁能想出一个不限制锁定时间的解决方案？

boost::interprocess::named_mutex named_mtx(boost::interprocess::open_or_create,lockName.c_str());

    while(true)
    {
        if(named_mtx.try_lock())
        {
            break;
        }

        if(!named_mtx.timed_lock(boost::get_system_time() + boost::posix_time::milliseconds(TIMEOUT_MILLISECONDS)))
        {
            named_mtx.unlock();
        }
    }
