Mesa is an open-source implementation of the OpenGL specification, a system
for rendering interactive 3D graphics.
Complete documentation on OpenGL usage and configuration can be found here:

This release has been rebuilt for LLVM 3.7.

Hi Yaakov,
we found a case where the 32bit is segfaulting
while dri-drivers-11.0.9-1
works fine.
For reference:

To replicate with octave is enough :
run from xterm
/usr/bin/octave-cli-4.0.1.exe
x=1:100;
plot(x,x)
as dri-drivers seems absent from mesa-debuginfo
I can not provide you a meaningful backtrace:

However I see that also mesa-demos segfault
$ cd /usr/lib/mesa-demos
$ ./quad-clip.exe
GL_RENDERER = Gallium 0.4 on llvmpipe (LLVM 3.7, 256 bits)
GL_VERSION = 3.0 Mesa 11.0.9
GL_VENDOR = VMware, Inc.
Segmentation fault (core dumped)
