Hi J-S,
Can you try to use a ref pointer instead of the regular pointer for
"osg::Shader* shader". I believe I encountered exactly this issue when
working on the PSSM, please see a patch that I sent +/- a week ago.
The shader was not cleaned up in the case of PSSM, and hence the new one
was not created.
bye bye
