[osg-users] Crash on first example - push_back call

[Jakob Ruhe]

Hi Adrian!

The tutorial should work. I just tested it by compiling it with Visual
Studio 8 and osg 2.4. I can tell from the error you get that you are
generating a debug build in Visual Studio. Are you sure that you also
link against the debug version of osg (osgd.lib, osgDBd.lib and so
on)?
What version are you running?
