Thank You, I noticed that in Windows changing Threading Optimization to ON in NVidia driver properties does remove the issue in OSG 1.2. Unfortuanately curent SVN version is still crashing. So suspicion that it may be NVidia seems well founded.

Bug(UNCLASSIFIED) Classification: UNCLASSIFIED Caveats: NONE I changed to viewer.realize(Producer::CameraGroup::SingleThreaded) and it does not crash. I changed back to viewer.realize(Producer::CameraGroup::ThreadPerCamera) and I get SIG32 signal. Unfortunately, I am using Nvidia, so I can't rule out the driver possibility, but it does crash on Red Hat Linux. Actually, outside of the debugger, it hangs on exit rather than crashes. The screen remains blue and I have to CTRL-ALT-DEL to interrupt the window manager (GDM).

Bug?(UNCLASSIFIED) Thanks, application does just that - its textured redish cube. But all i wanted to know if it crashes on exit in Linux. And it looks like it does ? Similar thing happens in Windows Can you test once again and check if changing viewer.realize to ( osg::Viewer::SingleThreaded ) instead of ( osg::Viewer::ThreadPerCamera ) removes the problem ?

Bug ?(UNCLASSIFIED) Classification: UNCLASSIFIED Caveats: NONE Greetings, I'm not sure what is supposed to happen with your app, but when I ran it, I got a SIG32 on the "return 0" statement. I used the 1.2 code. I'm running on a Dell x86-64 dual core processor with Nvidia Quadro FX-1400, driver version 1.0-8178 with Red Hat Linux. When I run the app, the display shows the cube. I spin it, then press ESC. It removes the cube, but sometimes doesn't return control back to the window manager. Sometimes it does return to the window manager. I ran it with gdb compiled with "-g". I tried using the breakpoint supplied in the code, but that's not a valid address in my executable.
