I modified the code to look like this:
//----------
[...]
OSG::RefPtr<OSG::TextureChunkPtr> pTexture(createTexture(false));
[...]
OSG::beginEditCP(m_pViewportPass2);
m_pViewportPass2->getTextures().push_back(pTexture);
OSG::endEditCP(m_pViewportPass2);
m_pViewportPass2->render(pAction);
OSG::beginEditCP(m_pViewportPass2);
for (int i = 0; i < m_pViewportPass2->getTextures().size(); ++i)
{
OSG::subRefCP(m_pViewportPass2->getTextures(i));
}
m_pViewportPass2->getTextures().clear();
OSG::endEditCP(m_pViewportPass2);
[...]
//----------
I tried it with both subRefCP and subRef as well as with and without
the clear. Each time, my app crashed. Probably because the subRef
decreased the ref-count from 1 to something which looked a lot like an
"unsigned -1".
I'll try to write that small sample app over the weekend.
Best regards,
Marco

Hm, that's not quite clear to me. Did you try manually subRef-ing the
pointers there instead of calling clear()?

That's always the best way to get a quick response. Reproducing the
problem is most of the time 80% of the effort, so if we can save
ourselves that part we're much more likely to give it a shot.
