[osg-users] osgVolume::MultipassTechnique use

Robert,
Here is a better looking stack trace on Linux. (I believe this stack trace
has gdb debug symbols enabled, it was a bit tricky to create and integrate
a build with DEBUG symbols in my environment here, apologies if I got it
wrong).
My guess is that the Matrixd object being inverted after the call to
MultipassTechnique::cull is a NULL pointer or something like that...is
there perhaps a property or something I'm failing to setup when using
MultipassTechnique that might cause that to happen?
No, I don't know whether the example works. My use of MultipassTechnique is
failing on a Mac and a Linux box within the software stack where I am, and
the stack trace looks the same on Mac and Linux. I can try to build the
example. In the build harness where I work, I'd have to do a bit of work or
else just build OSG from scratch to use the volume example.
Any thoughts at all based on this seg fault trace? Any leads would be much
appreciated, feeling stuck.
- Alex
