[Bug 344957] Re: [hardy] xorg crashes nightly; SIGSEGV in pixman-image.c

[Bryce Harrington]

** Description changed:

  Binary package hint: xorg
  
  xorg appears to be segfaulting every night.  It doesn't seem to happen
  at exactly the same time, so I suspect it's not e.g. an interaction with
  a cron job, and maybe has more to do with how long the computer has been
  idle.  I am running 8.04.2 (recently upgraded from 7.10, under which I
  didn't have this problem), and using the "radeonhd" open source driver
  (see below).
  
  (I also got nightly segfaults when I was using "fglrx" under 8.04,
  although I was never able to get a backtrace on those so I don't know
  for a fact that they were the same.)
  
  I am attaching a gdb backtrace, xorg.0.log, xorg.0.log.old, and
  xorg.conf. This crash appears to be happening in pixman-image.c.
  
  When the crash happens I get returned to the gdm login screen, and I can
  re-log-in without problems, but of course any applications that I was
  running at the time are unreachable and have to be manually killed.
  
  Thanks to anyone that can help!
