Although I noticed the segfault with mesa configured and built with :
make -j 8
Because I have never been able to produce a working offscreen VTK with
mesa configured this way, and since -fvisibility=hidden was added the
./autogen.sh way did not even build VTK untill the
cbf30fce322506bd43692617de9d201533f41532 change. and that was about the
same time that offscreen rendering stopped working for me no matter how
I built mesa, my git bisect script uses :
make -j8 linux-x86-64-debug
so -fvisibility=hidden is not added to the command line of the builds in
the git bisection.
