Sorry for bouncing this, but I'm getting some crashes which might be
vaguely related to this (in TextureChunk's destructor).
How are FCPtr's references handled when stored in Fields in general?

Hi all,
I'm a bit bewildered by the behaviour of shallowcopy(), as it does not
seem to update reference counts of fields holding field containers.
More specifically, I'm doing something like this: (in order to preserve
filter & wrap fields I figured I'd make a copy of the field).
TextureChunkPtr tc = [node->core->material->chunk];
TextureChunkPtr tc2 = TextureChunkPtr::dcast(tc->shallowCopy());
tc2->setImage(newImage); // subrefs (ok) & dellocates (!?!)
// add as new texture to material
material->addchunk(tc2, tc->getslot() + 1);
I suppose I could inc the reference count for all the fcptr-fields when
doing such copies... if that is the right way to do stuff. Just feels
like too much error-prone user-work here.
Mayhap it's just shallowCopy() I shouldn't use, but something else?
Best regards,
