NVIDIA Puts Out Two Drivers, Including For OpenGL 4.1
Yes, but it's written in C# and is buried inside the Win32 part of a 850KLoc, open-source project. (The Linux part thankfully uses a slightly different approach that doesn't crash, but the driver bug affects both operating systems). I can provide a link if you wish.
This is a 260.xx-specific bug, where the driver crashes under some very specific circumstancse:
1. you create two threads
2. you load OpenGL dynamically on thread 1 (instead of linking with -lGL)
3. you create an OpenGL context on each thread
If all three hold, the crash occurs as soon as you call MakeCurrent on either thread. If you load OpenGL before creating the 2nd thread, the crash doesn't occur.
The issue is known to Nvidia, we are just waiting for a fix (ever since 260.99 was released).
