Hi Bruce Clay
  According my experience,you can try to upgrade your display driver to the newest version,mostly the problem will disappear.

>   Just to be sure I pulled the latest git release and diffed it against the code I had and only found differences in commented headers.  I built the code as I had previously and got the same errors.  I am using the 32 bit version of 3rd party dependencies which is not the latest posted but only a 64 bit version of the latest dependencies is posted and I need a 32 bit app.

In this configuration, the program sometime crashed immediately with no scene display and other times ran fine.  It we still to unstable to leave in this configuration.

With this configuration, osgViewer never crashed but some of the other / larger apps still crashed.   I can not name those that crashed or where they crashed at this moment because I am installing Visual Studio 2015 and the installer won't let me run any version of Visual Studio while it is doing a setup.  It did still point towards a threading problem though.  I can check tomorrow when the install is finished.  Hope this sheds some light on the problem.  I will try vs2015 tomorrow as well.
