Red Hat Bugzilla – Bug 450554
GLX segfault crashes X
Last modified: 2009-07-14 13:43:23 EDT
Description of problem:
It appears the GLX module can segfault and bring down the X server. This tends
to happen on application exit (though not with all applications -- at the very
least, it affects SDL apps). The crash can be reproduced when booting from the
LiveCD of Fedora 9 as well.
All available updates as of 09-Jun-2008 were applied; no change observed.
Version-Release number of selected component (if applicable):
Reliable as clockwork.
Steps to Reproduce:
1. Start program (example one that triggers the crash is included below)
2. Exit program. X dies.
Entire X server goes boom.
X server does not go boom.
To verify that this was not due to some driver configuration issue, the program
was tested after booting from the F9 GNOME LiveCD. The crash is seen here as
well. Also tried with no xorg.conf file (i.e., letting X use its built-in
defaults). No change.
Test case that triggers the crash
using namespace std;
int main(int argc, char* argv)
SDL_Surface* win = SDL_SetVideoMode(512,512,24,SDL_OPENGL);

This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '9'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 9's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 9 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
