           Product: Mesa
           Version: git
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW

I have mesa up to 5f7d5d3ea3932ef6028b21bb22d8d28dbdd9fa9f (r600: use
AUTO_INDEX for draw - saves cmd buffer space )

When I run shadowtex demo with LIBGL_ALWAYS_INDIRECT=1, it asserts:

glxinfo lists r600 DRI as renderer, I can re-test with pure software, if
shadowtex really should work in indirect mode.
