Hi Robert,
Unfortunately the fix didn't address the crash I am encountering. The issue of
the dynamic cast in objectDeleted()
(\openscenegraph\src\osgUtil\CullVisitor.cpp) failing remains...
virtual void objectDeleted(void* object)
{
osg::Referenced* ref = reinterpret_cast<osg::Referenced*>(object);
osgUtil::CullVisitor* cv = dynamic_cast<osgUtil::CullVisitor*>(ref);
OpenThreads::ScopedLock<OpenThreads::Mutex> lock(_mutex);
RenderStageMap::iterator itr = _renderStageMap.find(cv);
if (itr!=_renderStageMap.end())
{
_renderStageMap.erase(itr);
}
}
I was going to define our object that inherits from the CullVisitor as an
osg::ref_ptr. Perhaps doing so will delay the freeing of the CullVisitor
object long enough within the CullVisitor destructor so that the problematic
dynamic cast will succeed. I am open to any other suggestions as well. I may
have to resort to just creating a small example program that reproduces the
issue.
Thanks,
Rick

Hi Robert,
Thanks for the update. I will try out the fix.
