Description Radek Liboska 2005-07-02 15:22:03 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050513 Fedora/1.7.8-1.3.1

Description of problem:
Some OpenGL 3D games like lsdldoom or q3demo crash upon starting with "Segmentation Fault" when the  kernel-2.6.11-1.35_FC3 default value (2) of /proc/sys/kernel/exec-shield is set.
$ echo 1 > /proc/sys/kernel/exec-shield
solves the problem.
(Graphic driver:
kernel-module-nvidia-2.6.11-1.35_FC3-1.0.7664-0.lvn.1.3
CPU: AMD Athlon)



Version-Release number of selected component (if applicable):
kernel-2.6.11-1.35_FC3

How reproducible:
Always

Steps to Reproduce:
1.cd /usr/local/games/doom
2../lsdldoom
3.
  

Actual Results:  ...
Fatal signal: Segmentation Fault (SDL Parachute Deployed)

Expected Results:  start the application

Additional info:

The information of the exec-shield should be emphasized. It is extremely tough task find the reason why many applications are dead after upgrade of the kernel.
