Greetings.
OpenSG 2.0 (64-bit Vista DLL) is crashing in its exit routines after
having loaded a ".wrl" file into a SimpleSceneManager. The app runs
fine until the window closes and the app quits. Also, it exits cleanly
if I use a hard-coded scene instead of loading from a "wrl" file.
It fails differently depending on whether I explicitly call osgExit(),
or let the atexit functions handle the cleanup, but it fails in either
case.
If I /don't/ explicitly call osgExit(), then the app fails like so:
Unhandled exception ... Access violation reading location
0xffffffffffffffff.

Some notes on the program structure:
* The ".wrl" file contains only a simple tetrahedron -- a single
IndexedFaceSet with no texture.
* I'm managing OpenSG from within my own DLL.
* MyDLL's entry function allocates an App object on the stack.
* The App's data members are:
OSG::SimpleSceneManagerRefPtr m_SceneManager;
boost::shared_ptr<Win32Window> m_Window; // NOT OSG::WIN32Window
std::string m_Name;
* The Win32Window's data members are:
HWND m_hwnd;
OSG::WIN32WindowRefPtr m_osgWindow;
boost::shared_ptr<Win32MessageController> m_msgController;
* The Win32MessageController's data members are:
OSG::SimpleSceneManagerRefPtr m_sceneManager;
* I call OSG::osgExit() just before the App object goes out of scope
and its d'tor is called. There are no explicit references to any
OSG objects beyond that point, but there is a chain of d'tors for
OSG::RefCountPtrs, OSG::RecordedRefCountPolicys, and
boost::shared_ptrs
* I note that there are two OSG::SimpleSceneManagerRefPtr's referencing
the same object, to be cleaned up in the d'tor chain. Is that a
problem? (And why would that be sensitive to whether or not the
scene was loaded from a ".wrl" file?)
Sorry for the length of this message.
Thanks for any news or advice.
