           Summary: Crash in World of Warcraft
           Product: Mesa
           Version: git
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Drivers/Gallium/r300
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: rankincj@googlemail.com


World of Warcraft is crashing again, after a few minutes fishing in Dalaran's
fountain.

After reverting as far back as:

commit 381d32af74e305041b5e75930a32795db94e0e15
Author: Tom Stellard <tstellar@gmail.com>
Date:   Sat Apr 2 23:14:12 2011 -0700

   Revert "r300/compiler: Remove obsolete compiler passes"

   This reverts commit 9f013a8233197d4a0482661cb37cfeac1a61b804.

   These passes are still need for non-GLSL paths like g3dvl and ARB
   programs.

I was able to fish in Dalaran's fountain for several hours, although the crash
was still present when I'd only reverted as far back as:

commit 437c748bf5072d2bded77a00c74c51cdb8b510e5

In between these two commits is c35572352e3e92683988ee8d151b47f4190d62f9, which
I have not tested.

If you just revert 437c748bf5072d2bded77a00c74c51cdb8b510e5, does it fix the
bug?

I've just experienced the exact same crash with this commit as HEAD:

commit c35572352e3e92683988ee8d151b47f4190d62f9
Author: Marek Olšák <maraeo@gmail.com>
Date:   Sun Apr 3 17:32:47 2011 +0200

    r300g: remove the redundant reference counter in radeon_bo

    We already have pb_buffer::reference::count.

No, the first bad commit seems to be c35572352e3e92683988ee8d151b47f4190d62f9.

I have finally captured the actual error when WoW crashes:

Should be fixed with aac4bae98651c928ce298aecf158b0aa1a7fabce. Reopen if you
still have any issues.
