Re: [vrjuggler-info] Trace of previous segfault

[Todd J. F. <to...@in...>]

I rolled back ConfigDefinition.cpp to 1.5 and ConfigDefinition.h to 1.6, 
and I get the same results.

Patrick, maybe you can give me some advice.  I want to move towards 
version 2.0 (I've been at 2alpha3), but I also need to keep my 
applications working.  Here's what I need:
- Clustering
- No scaling issues in OpenSG or OpenScenegraph apps

What recent version do you recommend?
