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

[OpenSceneGraph Users]

Hi Robert,

thank you for the reply. You guess point me out to some way I could do 
further problem analysis. 

 1.*could it be thread safety issue with the Windows iostream 
implementation?   - *that is a valid point I will check out this.

* 2.SingleThreaded to see if it's related to threading -  *I have tried 
this, app does not crash as far as I have tested.
 
* 3.disable the debug console output - *do you mean by disable this marco DEBUG_MESSAGE?  
I noticed a macro "OSG_NOTIFY_DISABLED" in include/osg/Notify. Shoud I just 
define this in that file Notify?

 Best Regards
 Yuan
