Re: Mesa 7.11.2 Segmentation fault

I think the linking issue is mischaracterized; it's not a Mesa issue but 
a VTK issue.  Any recent VTK will have trouble linking both libGL and 
libOSMesa.

I didn't necessarily mean the valgrind output is interesting for *me*... 
I think you should save the full log in a text file (e.g. 
'--log-file=mesa.vglog.txt') and attach that to the bug report you open. 
  It would be good if you could run with --track-origins=yes as well.

Good luck!
