OK I created a small standalone program that shows the crash (attached).
To trigger the crash:
1. Run debug version of osgmultiwindowtesttext. It will open 2 windows
(Viewers) that contain text "Scene1" and "Scene2"
2. Close one window -> it might crash. If it crashes, see debug info
Hi Robert, yes I'm working on a standalone test program now. Multithreaded
crashes are often hard to reproduce in a vacuum, but as soon as I have
something I'll post here.
I'm running on Win10, Nvidia GTX 980 (latest drivers), Visual Studio 2013,
OpenSceneGraph-3.6 branch.

Hi Ravi,
My guess is that the new text implementation isn't the cause of the crash,
only it's the straw that broke the camels back, and actually there is an
underlying limitation with the OSG w..r.t you specific usage case.
Could you create a small test program that reproduces the crash. Details
Hello all,
I'm seeing a crash on the OpenSceneGraph-3.6 branch that occurs when I have
two CompositeViewers that contain Text objects in their scenes. My
simplified scenario is this:
- 2 CompositeViewers, each in singlethreaded mode, but being run at the
same time in separate threads (via OpenThre
Robert,
thanks! I'll try this helper marco.
Cheers,

Hi Alexander,
Could you try either putting the mutex in the global scope or creating a
small initializer class that calls getDefaultFont() that gets constructed
in the global scope, the OSG has a helper macro for this so you could use:
OSG_INIT_SINGLETON_PROXY(InitDefaultFont, getDefaultFont())
Hi,
My osgEarth based application was crashing from time to time (3-4 times a day).
It was not easy to debug. But eventually I've caught the problem place in
Release with Debug info mode.
DatabasePager thread crashed in osgText/Font.cpp file in the function:

Thanks Robert,
I do realize it's tough to tell without seeing the code. Up to yesterday I
used osg 2.1, but just upgrade to 2.7.1 (bug still occurs). FWIW, I'm not
using the viewer setup in the examples, I use my own osgUtil::SceneView and
use cull & draw directly. Note I setup my viewport proper
Hi Pail,
The default setting of DataVariance is UNSPECIFIED. There has been
lots written on this topic, please go look at the archives.

Thanks Jean,
The adding / removing / deleting is because I am using it to enter typed
text. You're right, I don't have to actually delete the Text drawable each
time I'm finished entering text, but I do need to set it's text repeatedly
in response to my typing. I have a feeling it would crash any

Hi Chris,
With so few details about your viewer setup and scene graph usage the
best we can do is guess what you might have done wrong given other
common mistakes we see pop up - have the DataVariance recommendation.
Another thing you could try setting the threading model on the viewer

Hi Chris,
I create my Text in response to a keystroke, and add it to the scene.
The next keystroke removes and deletes it. Each time I create it, the
initial rendered text string does not change.
This is more of a workaround than an actual fix, but why are you
