[osg-users] seg fault with text->setText(mystring) called in NodeCallback

[DavidHornung]

Hello,
i have a seg fault because the osgText::Text::setText(std::string) is 
not thread-save.
It appears from type to time
Why get I this seg fault sometimes?

I have the following setup

class ObjectGroup : public osg::Group
{
...
    ObjectGroup()
   {
        ...
        text = osgText::Text;
        ....
        this->addChild(text);
        this->setUpdateCallback(new ObjectNodeCallback);
   }

//called from NodeCallback
   void updateText()
   {
         text->setText(myText);
    }

private:
    osgText::Text text;
    std::String myText;
...
};

class ObjectNodeCallback : public osg::NodeCallback
{
     //override
     operator ()(osg::Node* node, osg::NodeVisitor* nv)
     {
             osg::ref_ptr<ObjectGroup> obj = 
dynamic_cast<ObjectGroup*>(node);
             obj->updateText();
             traverse(node, nv);
     }
};


Cheers,
David
