           Summary: Xv crashes with new common allocator
           Product: xorg
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: daniel at ffwll.ch
         QAContact: xorg-team at lists.x.org


Latest xf86-video-ati master git checkout crashes X when using Xv. Afterwards X
starts up normally again, so there are no persistent effects to the crash.

Card is an X1950 Pro AGP on a 4 Core Opteron amd64 Linux machine:

The whole xorg stack (xorg, drivers, mesa, drm) is more or less latest git
master.

With git bisect I've tracked down the regression. It's introduced in the
following commit:

7daba77ded1c718e93ae8c372a39a6e85228d513 is first bad commit
