I’m having a similar problem, but only whenever I run an OpenGL application.
This is my kernel log right before and during a system crash.

Is your system stable in general? Does it pass memtest86+? Please check to make sure that the graphics board is firmly seated in its slot, that the external power connector is firmly attached, and that the heatsink and fan are free of dust and debris and that the fan is spinning.
Yes rock-solid otherwise. Even plays Seriuos Sam 3 for hours. It’s just minecraft
that seems to touch a sensitive spot somewhere. And hardware is clean and fans are all
spinning fine.
I get a lot of errors like the first one; the second one has been unique so far.
Just to be clear: playing minecraft works fine for hours on end, it’s minimizing/maximizing the application window which causes these errors! Especially on my 8800GT.
This is currently the most common crash, KDE-4.10 with compositing and only minecraft running.
Maximize and minimize the window a couple of times and it crashes with this. The offendinf function and offset are always identical:
SIGSEGV (0xb) at pc=0x00007f8bbe578078, pid=22137, tid=140238269200128
JRE version: 7.0_13-b20
Java VM: Java HotSpot™ 64-Bit Server VM (23.7-b01 mixed mode linux-amd64 compressed oops)
Problematic frame:
C [libnvidia-glcore.so.313.18+0x150f078] _nv005glcore+0x8af08
System is stable; had it continuously build libreoffice in a ramdisk over night without
any problems. Card is an 8800GT; on laptop with a Q4000M and single display it’s much more stable.
