[osg-users] Memory leaks with osg::ref_ptr

[Tamer El Nashar]

Any ideas why the class from the code below would cause memory leaks?  
I've read as many tutorials as i could find, to learn the proper use of 
the osg::ref_ptr, and i tried all the tricks up my sleeve.  However I'm 
still getting a memory leak in the member variable m_Text;

Thanks in advance.
