Hi Yaakov,
we found a case where the 32bit is segfaulting
while dri-drivers-11.0.9-1
works fine.
For reference:
https://cygwin.com/ml/cygwin/2016-04/msg00245.html

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
#2 0x439346c6 in gallium_dri!__driDriverGetExtensions_swrast ()
from E:/cygwin/lib/dri/swrast_dri.so
...
#12 0x43563ce9 in gallium_dri!__driDriverGetExtensions_swrast ()

#13 0x4abfa82c in opengl_renderer::set_polygon_offset (this=0x80610180,
on=false, offset=0)
at /usr/src/debug/octave-4.0.1-1/libinterp/corefcn/gl-render.cc:2916
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)
