Hi James,
Is there a reason the destructor for the Shader object is protected?
Like all classes derived from osg::Referenced, you're not supposed to
create them as normal variables. You use ref_ptr and new, like this:
osg::ref_ptr<osg::Shader> shader = new osg::Shader(...);
The destructor of classes derived from osg::Referenced are declared
protected to enforce this. There are probably other reasons, but that's
the net effect - you need to use new because if not, the compiler will
complain that the destructor is protected at the end of the scope; even
when you use new you can't delete them manually, so you need ref_ptr to
manage the ref count, and the (protected) osg::Referenced destructor
will delete the object automatically once the ref count goes to 0.
See include/osg/Referenced line 184 (in current trunk)

Hope this helps,
J-S
