Missing dynamic pointer cast in SkyDomeUpdateCallback

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Checkout and build current OpenSceneGraph (2014-08-20 16:15:36)
2. Checkout and try to build osgephemeris


What is the expected output? What do you see instead?
Compilation should work but error occurs:
osgEphemeris/src/osgEphemerisLib/SkyDome.cpp: In member function ‘void 
SkyDomeUpdateCallback::_callDrawableCallbacks(osg::Geode*, 
osg::NodeVisitor*)’:
osgEphemeris/src/osgEphemerisLib/SkyDome.cpp:71:92: error: invalid conversion 
from ‘osg::Callback*’ to ‘osg::Drawable::UpdateCallback*’ [-fpermissive]
                     osg::Drawable::UpdateCallback *updateCallback = dbl->getUpdateCallback();
                                                                                            ^
osgEphemeris/src/osgEphemerisLib/SkyDome.cpp:71:92: error: cannot convert from 
base ‘osg::Callback’ to derived type ‘osg::Drawable::UpdateCallback’ 
via virtual base ‘osg::Callback’


What version of the product are you using? On what operating system?
Current SVN Rev 33 on Debian Jessie. Compiled with g++ 4.8.3 and CMake 2.8.12.2.


Please provide any additional information below.
In SkyDome.cpp line 71 replace:
osg::Drawable::UpdateCallback *updateCallback = dbl->getUpdateCallback();

with

osg::Drawable::UpdateCallback *updateCallback = 
dynamic_cast<osg::Drawable::UpdateCallback*>(dbl->getUpdateCallback());
