I wonder if the databases themselves are corrupted. On 6/28/07, [EMAIL PROTECTED] <[EMAIL PROTECTED]> wrote:
Hi Robert,
I forgot to mention that I have checked this behaviour on different
machines, with different
graphic cards (Nvidia 7800 GTX and Quadro FX 3000 / FX 4500) and different
Nvidia
drivers.
I compiled all OSG / Producer / OpenThreads code with the standard
settings (O2), and I
also tried to recompile without optimizations, to no effect (apart from an
obvious performance drop).
Today I have installed the newest drivers from Nvidia (100.14.11) but I
keep having random
crashes.
This is really causing a lot of headache here, because we are very pleased
with OSG performance,
and our applications really fly (!!),
I'll keep investigating...
Thank you
Andrea Damiano

Oggetto: Re: [osg-users] Random crashes under Linux with PagedLOD
databasepaging
Hi Andrea,
The interaction with the NVidia control panel really suggest an OpenGL
driver bug.
The stack traces suggest a database reading bug...
Is there a chance it could be gcc bug though... try and compile with
-O2 rather than -O3 to see if makes a difference.
Another long shot might be a physical memory error, it doesn't happen
very often, but it has happened in the past that flaky machines have
caused weired memory related crashes.
FYI, I develop under Linux, on a dual core machine, and test on dual
7800GT + paged database regularly and don't see crashes on any of the
terrex or osgdem generated databases I have.
Robert.
