          Priority: medium
            Bug ID: 69805
          Assignee: dri-devel@lists.freedesktop.org
           Summary: flightgear crashes on r600 (rs880)
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: marvin24@gmx.de
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: git
         Component: Drivers/Gallium/r600
           Product: Mesa

flightgear 2.12 crashes on git mesa. Works with R600_LLVM=0. I initially
thought it is due to missing trig functions, but after applying a workaround
(from some other bug), it still crashes, so this must be something different.
