[osg-users] [osgPPU] osgPPU HDR problem with cycles

I am actually porting your HDR sample in my application. 
In this example, you are using a cycle dependancy (between adaptedLuminance and adaptedLuminance child) to get the previous frame average luminance scene. 

When I use your application, it works well. 
But in my application, I have got stack overflow assert in the recursiv osg function group::SetThreadSafeRefUnref(...) because (I guess) it is looping on the cycle without any chance of exit 

Code:  � Select � � Expand �
void Group::setThreadSafeRefUnref(bool threadSafe) 

    for(NodeList::const_iterator itr=_children.begin(); 

I did deeply have a look on your sample but I do not understand why it is working in your example ... 
What did I forget ? 

I am using osgPPU 0.4.0 with OSG 2.8.2
