For historical reasons the loaded terrain is placed under a PAT node
that is not really in use. So I don't think this is the issue. However,
after putting the search lights on, I found an obsolete ReadFileCallback
that adds an additional imagelayer to each tile when its loaded from
disk. I have now removed the obsolete callback and I hope that this
means that the intermittent crash won't show its ugly face again...:)
Best regards,
John

John,
Does this happen in your app or in just in osgviewer with the vpb
database? I see a PositionAttitudeTransform in your stack trace and
VPB doesn't generate databases with PATs so I'm wondering if it's
something else going on.

Hi all,
We currently have an crash situation that we unfortunately cannot
consistently reproduce, but when it happens it always occurs in
osgTerrain::Terrain::traverse(osg::NodeVisitor&) (see below for
stack trace). The terrain is a "standard", but fairly large
osgTerrain database built with VPB. The osg version is 3.0.1 and
the application runs osg in SingleThreaded mode.
I haven't checked for changes in trunk yet, but has anyone else
seen a similar stack trace lately?
Best regards,
John
