New: Intermittent Xorg crashes with compiz

htt
p://bugs.freedesktop.org/show_bug.cgi?id=13391

           Summary: Intermittent Xorg crashes with compiz
           Product: Mesa
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/i830
        AssignedTo: dri-devellists.sourceforge.net
        ReportedBy: bgamarigmail.com


When running compiz Xorg will crash after some period of
time. I have thusfar
been unable to establish exactly what user action triggers
the crash (it seems
many actions will). While frequently Xorg.0.log doesn't
actually give a
backtrace (strangely), I have attached a log where the
backtrace did get
written.

I've been compiling Mesa with -ggdb -g3 -O1. Can anyone see
any reason why my
stack traces don't have line numbers?

The backtrace in the log file never provides more
information. Use something
like gdb.

It turns out that attachment 12728 was actually from another
bug pertaining to
compiz. In this case, compiz crashed, which then triggered
another bug in the
intel driver, causing Xorg to crash. This is a very
reproducible behavior (for
me) so I created bug 13409 to track it.

Otherwise, I do not believe I've seen a crash like the one
in attachment 12719
since the initial incident.

Well, it seems that the apparent cessation of crashes due to
this bug was a
mere coincidence. Just in the last day, compiz has crashed 7
times.
Unfortunately, the server rarely provides any indication of
an actual error in
the log and almost never provides a backtrace. I'll try and
get a backtrace
from gdb later today
