Hi Robert,
Good. This also works for me in the osgterrain-crash-program.
I've updated our patches to match this fix, and our internal tests also
pass.
Thanks for taking the time and sharing this great software!

Hi Robert et al.,
I finally got the time to investigate the code (osgTerrain/Terrain.cpp).
As I see it, it is not necessary to introduce a new data structure to hold
the list of update tiles. The issue was that a TerrainTile could be partly
destructed but not unregisterTile:ed, when an
is that we'll need to introduce a form of set that
manages a list of observer_ptr much in the same way that the
ObserverNodePath is managed, so we'll need an equivalent
ObserverNodeSet class.
Robert.

Hi Robert,
Ok, I see the problem. If I get the time later today I will look into the
code in depth.

Hi Robert,
This explains the behavior we have experienced, the crashes we observed were
notoriously difficult to reproduce in a debug environment (gdb, valgrind,
etc.).
Thanks for taking your time to investigate this!

Hi,
We have been looking for a hard-to-reproduce crash in our software that
seems to originate from a double delete inside osg. I have (finally) been

_exaggerates_ the usage pattern that crashes our application.
