Hi again,

I've identified one crash in the GLBufferObject::bindBuffer due to an uninitialized _extension member. It seems, it gets destroyed somewhere in the middle. Unfortunately the GLExtensions object doesn't have a declared destructor, so chasing this down is harder than I thought.
I'll analyze futher.
Btw. I've already rebuild cleanly and used the HEAD for testing, but it seems the behaviour stays the same.

Cheers
Sebastian
Hi Robert,

would you expect problems with old osgTerrain databases (build with ~3.2.0, osgb format)? I have some strange behaviour with a huge database, which simply not displayed anymore and somehow breaks state (See attached picture).
Also there is a warning coming from an optimzer I guess:

Warning: CollectLowestTransformsVisitor::removeTransforms() error, encountered a NULL Transform pointer

A second, much smaller database is sometimes displayed, but crashes the viewer sometimes.
I've attached it, could you please try to load it?

It is really hard to find the culprit.

Any hints?

I'll investigate the issue further ...

Cheers
Sebastian
