[osg-users] osgViewer crashes at inserting string into stream inside Renderer::draw() (Win10, osg3.2.0, compiler vc10)

[OpenSceneGraph Users]

I have seen this issue in the past when linking libraries built in debug mode with an app in release mode, or vice-versa, so that is the first thing to check. Since the assertion is in the debug C++ runtime (with the “d” suffix”) your app must also be built in debug mode with the same runtime.

Kind regards,
Phil
