Segfault when running GPU Computing SDK examples

Hi,

I installed the latest developer drivers (195.36.15) for my 8600M GT NVIDIA card, the toolkit for ubuntu (I am using Kubuntu 10.04) and the latest GPU Computing SDK. I managed to compile all the examples using gcc 4.4.3. The problem is that when I try to run an example, I get a segmentation fault. Here’s what I get in gdb when I try to run deviceQuery:

codebox run

Starting program: /home/frounk/NVIDIA_GPU_Computing_SDK/C/bin/linux/debug/deviceQuery

[Thread debugging using libthread_db enabled]

Program received signal SIGSEGV, Segmentation fault.

(gdb) p cOverRideName

$1 = 0x4128a2 “deviceQuery.txt”[/codebox]

It seems to crash in strlen, but I really doubt the problem is with the call to strlen and cOverRideName seems to be a valid string. I have the latest drivers installed and I can’t seem to find what is causing the crash. Has anyone else encountered this problem (and hopefully solved it!)?

Thank you
