[osg-users] Moving from 3.4.1 to 3.5.7 breaks my "hardware instancing"

[Andrew Cunningham]

Hi Robert,

Updating to 3.6.3 fixed the problem! 

I did find a possible subtle issue with 3.6.3 when OSG_NOTIFY_LEVEL=DEBUG.
No issues at other OSG_NOTIFY_LEVELs.

I am getting a crash at program exit at this line, called from GraphicsObjectManager::~GraphicsObjectManager


std::ostream& osg::notify(const osg::NotifySeverity severity)
{
    if (osg::isNotifyEnabled(severity))
    {
        getNotifySingleton()._notifyStream.setCurrentSeverity(severity);
        return getNotifySingleton()._notifyStream; <---crash here
    }
    return getNotifySingleton()._nullStream;
}

GraphicsObjectManager::~GraphicsObjectManager()
{
    OSG_INFO<<_name<<"::~"<<_name<<"()"<<this<<std::endl;
}


My suspicion is that some "singletons" are getting destroyed in such an order that the "NotifySingleton" is destroyed before , say, the osg::ContextData is destroyed.

Anyway, it's a minor issue and does not affect release code.
