I've been able to reproduce this problem and workaround it by select --SingleThreaded on the osgshadow command line, so it looks like a threading issue with ParallelSplitShadowMap. > * osgshadow --sv : crashes.

Could you get a stack trace? Could you try running osgshadow single threaded like above to see if the crash goes. The quality issues mainly revolve around problems with very few shadow casting models being perfect manifold geometries. Without a manifold geometry the silhouette edge detection ends up with errors. I'm not sure what to do about these issue. It's certainly not something that can be tackled in 2.8.2 though. -- For both these issues I suspect a quick workaround of setting the threading model to SingleThreaded of r --pssm and --sv would more use a step forward. Properly fixing both these issues would likely require API changes so may well be inappropriate on these grounds. Thoughts?
