        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: GLX

this happens with current git (cd601513f5ff4f488a6f6527bb033e39ee62ffda), x
server 1.7.7. any attempt to create indirect context causes segmentation fault: 

Core was generated by `glxinfo -i'.
Program terminated with signal 11, Segmentation fault.

(old->psc is NULL). direct rendering contexts are fine.
