[osg-users] loading vrml segfault

This page indicates that OpenInventor only supports VRML 1.0 files. (http://www.openscenegraph.org/projects/osg/wiki/Support/UserGuides/Plugins) And from my own experience, OpenVRML only supports VRML 2.0 files. Can OSG handle both of these libraries at the same time?
I am a little doubtful since the VRML file must be parsed before it can be determined if it is VRML 1.0 or VRML 2.0. And OpenVRML segfaults when trying to load a VRML 1.0 file.
Does anyone have any experience supporting both VRML 1.0 and VRML 2.0 file types?

I tried your wrl files using osg with the coin3d plugin (alternate for
some of what openvrml does) and got predictable results, given your post.
When bombing on the Bad.wrl file, coin kindly provided the following:
% osgviewer Bad.wrl
Coin read error: Unknown field "mesh" in "VRMLShape"
Occurred at line 5 in Bad.wrl
osgviewer: No data loaded
Maybe this will help?
