Hello, I have encountered a crash bug when re-adding an update callback that has nested callbacks from OSG trunk's revision 13155. What seems to happen is that the nested callbacks are not cleared when a callback is removed from the middle of the nestedcallback linked list, causing a stack overflow.
Example code: osg::NodeCallback* callback1 = new osg::NodeCallback(); osg::NodeCallback* callback2 = new osg::NodeCallback(); osg::NodeCallback* callback3 = new osg::NodeCallback(); osg::Node* myNode = new osg::Node(); // Callback order: 1 myNode->addUpdateCallback(callback1); // Callback order: 1 -> 2 myNode->addUpdateCallback(callback2); // Callback order: 1-> 2 -> 3 myNode->addUpdateCallback(callback3); // Callback order: 1 -> 3 // Removing the second callback will not remove the nested callback from callback2 myNode->removeUpdateCallback(callback2); // Callback order: 1 -> 3 -> 2 -> 3 -> 2 ->3 ->2 ( cyclic nested callbacks) myNode->addUpdateCallback(callback2); Is there a reason not to clear the removed callback's nested callbacks? If there are reasons that the removeUpdateCallback should not remove the callback's nested functions, I think this behavior should be documented. Thanks, David
