Hi,

I don't see that here (MacBook with Leopard), it runs fine. I think I

have had a problem like this before and it ended up being related to
the OSG plugin search path. Make sure you only have one set of plugins
and that OSG and FlightGear are successfully finding them.
Seems to be OK at least nobody's complaining about anything i.e. 'fgfs
--log-level=debug' and OSG_NOTIFY_LEVEL don't give away anything.
Are you using the released OSG framework or did you compile OSG yourself?
Compiling myself from svn, as library not framework.
I'm pretty confident that the OSG build is OK as I'm using it for other projects
as well.
I've attached a gdb backtrace of the crash along with some detail of the images
it's crashing on (cirrus.rgba). As you can see the crash is actually in the
OpenGL driver
(gldAllocVertexBuffer..gldGetTextureLevel..gleGenMipmaps..glTexImage2D) called
from osg::Texture::applyTexImage2D_load().
The texture and image look fine so maybe this is completely unrelated to the
actual problem. If it's the first texture download it could just as well be a
GL context problem...
I'm just getting my feet wet with the codebase so any help/hints etc. are
appreciated.
Cheers!
