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

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:
#0 0xfc6d00a0 in ?? ()
#1 0x43934357 in gallium_dri!__driDriverGetExtensions_swrast ()
from E:/cygwin/lib/dri/swrast_dri.so
[snip]
> #14 0x4fc1ae48 in glutJoystickGetCenter () from /usr/bin/cygglut-3.dll
Corinna,
I'm seeing this as well. Any idea why gdb is using with dlopen()ed
modules? This is preventing it from finding the split debuginfo.
