yes, that may be the case and in most cases the objects involved will be
needed until the program exits (at which point the runtime/OS deletes
them anyway or at least reclaims the memory).

well, I think there are other, steeper points in the learning curve for
OpenSG beginners and while these cases are indeed memory leaks they are
fairly mild IMHO, because they only occur at the point when the
application exits anyway. That being said, I agree this should be fixed.

well, OpenSG is an open source project and I'm more than happy to accept
patches that correct these issues. As I explained, from my point of view
this is not a very high priority problem and it may be quite a while
before someone gets around to look at it.
So if you want to make sure that it gets dealt with, you have the
following options:
- file a ticket on the OpenSG website (opensg.vrsource.org) so this at
least will not be forgotten - due to spam you'll need an account to make
changes/open tickets on the site, ask here and I'll create one for you.
- write and send a patch to this list; the fastest way to get the
problem resolved.
- or you can do nothing further and hope somebody considers this a
problem that should be fixed rather sooner than later and writes a patch.
Cheers,
Carsten
