Hi Betrand,
There is known NVidia driver bug related to extensions, there has been
plenty of discussion about it over the last six weeks and a workaround
for it checked into CVS, so try the CVS version.
It might not be the NVidia driver bug of course... but you should at
least try the CVS version to see if things are fixed.

Hi all,
I get fatal error on basic graphics cards
I have the same problem on linux and mingw targets with all gui
(sdl,qt,producer,java).
I use OSG1.2 (Rev2)
Nvidia Geforce 4 MX400 is an example.
it is not a good card and it doesn't support all extentions.
with the osgDepthShadow example
the error messages are :
FRAGMENT glCompileShader "" FAILED
glLinkProgram "" FAILED
GraphicsContextImplementation::realize
it seems be a normal message because the card has bad performances.
but when the program is going to draw, I have a segfault in OpenThreads
library
the stack trace :

if I enable INFO mode for the osg trace, I have this informations before

I have exactly the same error (segfault) with the osgPrerender example
except this three lines.
FRAGMENT glCompileShader "" FAILED
glLinkProgram "" FAILED
GraphicsContextImplementation::realize
witch doen't appear in this example.
My question is : What is the best solution to avoid a segfault in all case
...?
Thanks in advance.

Bertrand.
