--- Comment #15 from Barto <mister.freeman at laposte.net> ---
I didn't manage to find the faulty commit in llvm 3.8, the bisecting process is
very slow and difficult ( I have a slow PC and there are a lot of svn revision
to test ),

in fact I think Roland is right, the problem could be mesa 11.0.2 and not LLVM
3.8 if some LLVM functions are used in a bad way by mesa 11.0.2,

it would be nice if someone who has a good knowledge in r600 driver can make
some investigations, we have a gdb backtrace, we know that the problem occurs
when a program uses the openGL function "glRasterPos2i()", and the problem
occurs also when we use the 100% software mode ( export LIBGL_ALWAYS_SOFTWARE=1
),

and of course the problem occurs only with LLVM 3.8 libs ( and at least with
the r600 driver ), there is no problem with LLVM 3.6.2, 

it would be great if this bug can be solved before LLVM 3.8 will hit others
linux distros ( like ubuntu )
