Hi all.
I got memory leak with OpenSG1.8 in debug mode on windows/VS2005.
To reproduce the problem, simply comment out some code of 01hello.cpp, like this
// Init the OpenSG subsystem
osgInit(argc,argv);
/* commented out
// GLUT init
int winid = setupGLUT(&argc, argv);
// the connection between GLUT and OpenSG
GLUTWindowPtr gwin= GLUTWindow::create();
gwin->setId(winid);
gwin->init();
// create the scene
NodePtr scene = makeTorus(.5, 2, 16, 16);
// create the SimpleSceneManager helper
mgr = new SimpleSceneManager;
// tell the manager what to manage
mgr->setWindow(gwin );
mgr->setRoot (scene);
// show the whole scene
mgr->showAll();
// GLUT main loop
glutMainLoop();*/
Then I checked VS memory leak by
MS function "_CrtMemDumpAllObjectsSince( NULL );"
It prints a long memory leak list, like this
{203} normal block at 0x02576B38, 32 bytes long.
Data: < oW ( > 90 6F 57 02 C8 09 90 02 28 08 90 02 CD CD CD CD
{202} normal block at 0x02576A00, 248 bytes long.

0x025767D8, 56 bytes long.
Data: < 8 8 > EC F8 38 10 E8 F8 38 10 00 00 00 00 00 00 00 00
But 01hello.cpp itself doesn't have memory leak, what I have done is
to comment all lines except osgInit()
So do I always have to create a GLUT windows to avoid memory leak?
Those memory leak are in osglog.cpp, which codes are supposed to clean
up those memory block?
Thanks!
Pan
