Unless someone here has the same video card, driver (+version), and
can reproduce your problem, I'm not sure you'll get much response 
here beyond the advice already given.  Certainly it is possible that
there is a video driver issue and that would certainly be specific to
the card in question.  But it's also possible that your program is 
causing a problem for the video driver.  It's also possible that there's
a bug elsewhere (i.e. gcc) which is contributing to this failure.  But
the answer to where the problem actually lies will come from some analysis.
Then again, there might be someone here on the list that has seen exactly
this problem and will pipe up with a solution.  It's my impression that if
that was the case, you would've heard from that person already.  So I'm
recommending you don't hold your breath waiting for that nice, simple 
solution to come your way. ;-)

Subject: Sementation fault in OpenGL application


Earlier I had posted a message concerning I segmentation fault I get 
when I build an OpenGL application using the GCC compiler on Cygwin.  I 
have since discovered that the debugger spits out some information when 
the segmentation fault occurs.  The is what it says:

Program received signal SIGSEGV, Segmentation fault.
0x6966190c in nvoglnt!DrvSetPixelFormat ()

I have a 64 Megabyte nVidia GeForce 3 video card on my system.  The 
debug message implies the error is occuring in the video driver.  I do 
not know what would be causing this, especially when the program runs 
fine when built with other compilers.

Can anyone offer any help on this matter?
