          Assignee: dri-devel at lists.freedesktop.org
           Summary: r600g: segfault with Kerbal Space Program
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: corey at octayn.net

Unfortunately the game is closed source and stripped, so I don't have more
information, but the backtrace I get is:

I have a trace but it's very large (>500MB) and it doesn't reproduce the crash.
I haven't seen anyone else report the crash. The crash happens on stable mesa
too.

I can reliably reproduce by selecting the first two menu options in the game
launch (Start Game and Settings). The previous versions of the game worked.
