Running latest FlightGear git version on openSUSE 13.1 with
Mesa-10.1~git20140110-1.1.x86_64, libLLVM35-3.5~svn20140107-1.1.x86_64,
llvm-r600-3.5~svn20140107-1.1.x86_64, libdrm2-2.4.99~git20131225-1.2.x86_64 and
kernel 3.13.0-rc7-6.g57a2f1c-desktop on a Radeon HD 5670 I get segfaults at
seemingly random points. The backtrace always looks like this:

Is this a bug in Mesa or more probably in FlightGear?
