Hi Robert Your crash is down to retaining a c pointer to an object that has been deleted. This dangling pointer issue is exactly why smart pointers are used in modern C++ application.
Lots has been written about ref_ptr usage here over the years, as well as docs and osg books that discuss it. So please do some of some background reading. In your own app you will either replace the c pointer usage with either a ref_ptr or observer_ptr.

So, i'm using removeChild, as it should be and got crash.

I've commented out removing child and there is no crash. And cannot find cause of that. Is it right way to do such kind of operation as removing node from scene? > > Thank you! > > Cheers, > Robert > > ------------------ > Read this topic online here: > http://forum.openscenegraph.org/viewtopic.php?p=60400#60400 > > > > > > _______________________________________________ > osg-users mailing list > [email protected] > http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
