Hi Gordon,

Thanks for the suggestions.  I am working in release, and I don't have any of 
the debug libs on my machine.  I re-extracted all osg files just in case 
something got corrupted.  I cleaned and rebuilt the application.  Didn't help.

However, I started a new Visual Studio project, copied all the settings over 
exactly, and now it works fine.  This makes me pretty confident that the issue 
is not to do with OSG but rather with Vis Studio, but I'm completely at a loss 
as to what the problem actually is - nothing short of creating a fresh project 
fixed the issue.

Just for the sake of completeness I want to share what I discovered about where 
in the code I could cause/not cause the crash:

Having 5 or fewer osg::Vec3d or Vec3f (up to 5 of each) class members was safe 
- no crash.  A sixth of each, however, lead to the program crashing when trying 
to create a Group.  I put a Node directly in front, the node was created 
successfully, it was still crashing on Group.

Again, I don't think the issue is with OSG - and I don't think I got libs mixed 
up, since I don't really have any stale libs on the machine.  Have other Vis 
Studio users experienced anything like this?  I suppose I just have to keep in 
mind that when weird stuff happens I can try creating a fresh project but that 
seems like a weak solution.



Cheers,
Tom
