<pre>I use archlinux 64 bits, graphic card : amd radeon HD4650 Pcie, cpu : intel
pentium dual core E6800 3.33 Ghz,
when building mesa 11.0.2 with llvm 3.7.0 version then a bug will occur with
the r600 driver when a program uses the openGL function "glRasterPos2i()", for
example the test program "tunnel" provided by the mesa-demos package, this
program will crash with the error "illegal instruction",
flightgear 3.4 will also crash at startup ( because it uses the glRasterPos2i()
function ),
the workaround is to build mesa 11.0.2 with the previous version of LLVM (
3.6.2 ), there is no bug if LLVM 3.6.2 and llvm-libs 3.6.2 are used during the
build of mesa 11.0.2,
I create first a bugreport in mesa website :
<a href="https://bugs.freedesktop.org/show_bug.cgi?id=92214">https://bugs.freedesktop.org/show_bug.cgi?id=92214</a>
I thought it was mesa 11.0.2 the culprit but in fact it's llvm 3.7.0 the real
culprit,
something is wrong in llvm 3.7.0,
I use also gcc-multilib 5.2.0-2, glibc 2.22-3, maybe the combination between
glibc 2.22-3 and llvm 3.7.0 is not good</pre>
