Hi Don,
There's a significant new clue here. Two of my three systems that crash
with
osgviewerQT --QOSGWidget cow.osg
are multi-processor systems. The third is a very fast single core Xenon.
All they systems where there's no crash are single processor systems.
Is anyone else able to run this demo on a multi-core system?
I just ran
osgviewerQT --QOSGWidget cow.osg
on my Windows Vista SP1 machine here, which is a quad-core Intel Q6600
with 3GB RAM. Qt 4.4.3, NVidia driver 182.06, OSG from SVN (today).
No crash here everything looks good. Of course none of your machines is
Windows so that doesn't help you much. :-(
Sounds to me like a driver problem. That'll usually be the case when the
exact same program runs fine on a certain number of machines but not on
others. Any chance you can try to revert to a previous driver or try a
new one?
If it feels to you like it could be related to multi-processor or
multi-core, I know for a fact that NVidia corrected some bugs in the
threading of their drivers lately, so perhaps a newer driver would get
you those fixes. I know installing drivers manually is a hassle but at
least it will give you an idea of whether that's the problem, until the
given driver version filters down from the package repositories...
Hope this helps,
J-S
