Hi Jonas,
This is most certainly a bug, which I'm delighted you've picked up -
its now fixed and checked in to SVN ;-)
The problem is that _threadsRunning was an uninitialized variable,
something I obviously missed in dev of 2.0, probably due to this
variable being a later addition. I've just gone through
CompositeViewer and can't spot any more uninitialized variables. I'll
go a double check the other Viewer classes as well.

Hi,
I have a problem with CompositeViewer. I've tried to get the
osgcompositeviewer example running in a threaded mode, but when I select a
thread model different fom SingleThreaded (ThreadPerCamera or
ThreadPerContext), the example still only runs with one thread. After
examining the code in CompositeViewer.cpp, I've found that the
_threadRunning variable is not initialized by default. So I made a new
class, inheriting from CompositeViewer, where I set _threadsRunning to false
and now it works. The code I wrote is the following:
#ifndef _NEWCOMP_H_
#define _NEWCOMP_H_
#include <osgViewer/CompositeViewer>
class NewComp : public osgViewer::CompositeViewer
{
public:
NewComp() : osgViewer::CompositeViewer() {_threadsRunning = false;}
};
#endif // _NEWCOMP_H_
Am I missing something or is this a bug?
I'm using OSG 2.0, RHEL5.
