Hi,
my OSG program crashes on end:
Thread 0 Crashed:
0 com.apple.agl 0x91e52a71 aglDestroyPixelFormat + 60
1 libosgViewer.65.dylib 0x00688c16
osgViewer::PixelBufferCarbon::closeImplementation() + 150
2 libosg.65.dylib 0x092a012f
osg::GraphicsContext::close(bool) + 1019
3 libosgViewer.65.dylib 0x00688e35
osgViewer::PixelBufferCarbon::~PixelBufferCarbon() + 47
4 osgnode.so 0x08c65f7b
avg::OSGNode::disconnect(bool) + 475 (Referenced:183)
The crash isn't really reproducible, but it happens only on a mac,
never under linux.
What's irritating me (besides the crash itself ;-)) is that
PixelBufferCarbon::closeImplementation() is called twice. Here is the
osg logging output with output added to the closeImplementation call:
Viewer::~Viewer():: start destructor getThreads = 0
close(1)0x1ef4f600
Releasing GL objects for Camera=0xa0d000 _state=0x3ab730
Closing still viable window 0 _state->getContextID()=0

Doing discard of deleted OpenGL objects.

_pixelformat: 0x1ef4f728
close(0)0x1ef4f600
GraphicsContext::unregisterGraphicsContext 0x1ef4f600
Done destructing osg::View
The crash happens (when it does) at the second
PixelBufferCarbon::closeImplementation line.
Any idea what I might be doing wrong? The logging output is a response
to dereferencing the Viewer - nothing more.
Cheers,
Uli
