[osg-users] Are there features to help detect bad data?

[OpenSceneGraph Users]

Hello all!

We've recently been having some intermittent crashes ("hangs"--Windows 
shuts down the process after a 2 seconds freeze in the graphics API) 
occurring in the nVidia's OpenGL dll. Google searches revealed that this 
can occur if we supply bad data to OpenGL. 

Are there features in OSG to detect such incorrect data in our models? 
Concurrent vertices, bad normals, bad UVs, etc.--stuff that could be 
correct or incorrect if defaulted (the crash is intermittent)?

We're using OSG 3.6.3, we read .flt files and convert them to .osgb with a 
convert tool of our own (using OSG), then we read those .osgb in our app. 

Thanks!
