            Bug ID: 85267
           Summary: vlc crashes with vdpau (Radeon 3850HD) [r600]
           Product: Mesa
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW

          Assignee: dri-devel@lists.freedesktop.org
          Reporter: arthur.marsh@internode.on.net

I'm using version 10.3.1-1 on Debian of most mesa-related packages and Linux

This looks like a use-after-free bug in the Mesa r600g driver. Can you report
this upstream at https://bugs.freedesktop.org/enter_bug.cgi?product=Mesa ,
component Drivers/Gallium/r600?
