I'm looking into some segfaults in VTK's Offscreen tests. These failures appeared about the time that I switched from building mesa with the "make linux-x86-64" target and moved to buiulding mesa with :
./autogen.sh \
--with-driver=xlib \
--disable-gallium \
--without-demos
make
It was also at this time that libOSMesa went from being linked against
libGL to being linked to mesa internal static libraries.
I build VTK and mesa from their development repositories every night.
This is what gdb has to say after the segfault.
