I have been beating my head against the wall trying to figure out a
bug in our application and I don't know if I understand enough about
how OpenSG works in order to find the bug. The basic idea is that our
application creates some geometry in a background thread, and then
syncs that geometry into the OpenSG scene graph in the primordial
thread. Later on the geometry is removed from the graph and deleted.
While trying to delete the object that contains the geometry I get the
following stack trace. It appears that while trying to clear the
geometry properties there is an invalid pointer access. Does anyone
have any ideas and/or guidance as to what could be causing this?
