Hi Sean, The first I spotted watching your stacktrace is that your are mixing debug with release libraries. AFAIK on windows mixing debug and release always gives problems, so the best you can do if you want to debug your code is build osg in debug or build your code in release with debug symbols.
Cheers, Rafa. 2012/5/9 Sean K <[email protected]>: > Hi, > > I took a look at your code. > > It looks good.
