[sldev] VWR-586 still in source?

[Patrick Ozer]

Hi All,

I am new in the mailing list, so a short intro.
My name is Patrick Ozer, I am a graduate student (MSc Artificial 
Intelligence)from the Netherlands and doing my
internship at Philips Research. I am involved in a project about SL for 
Philips Research, Philips Design and McKinsey & Co.

I compiled the source code (from 1.18.0.6 to 1.18.2.0) and got SL 
running and succesfully added my changes  to the source,
which were needed for my project. (all under Windows!)

But after a while of usage the viewer crashes. I checked my code and the 
flaw isn't in there. To be sure I redid compilation
with the source only and the problem still occurred. After compiling in 
ReleaseNoOpt and debugging, it looks like it is the VWR-586 bug,
which was solved I thought?? Another piece of info. After making an 
installer out of it it still crashes (duh). But after trying it on my PC
at home, or my laptop is worked just as the original SL viewer. After 
checking on other PC's, the viewer only crashed on some systems
all with a 'Buffer Overrun detected' notification. Most of the time 
after a while, and after the first or a couple of crashes, short after 
each other.

I think there is a problem with OpenGL, but I am no expert. In the call 
stack, before the usual stack with the VWR-586 bug the nvoglnt.dll
is listed a couple of times. The PC has a NVIDIA Quadro FX graphics 
card. This one caused problems earlier I thought.

Can anyone help me with this, or has someone had the same problem?

thanks in advance,

Patrick
