I have a program (VICE; see http://vice-emu.sourceforge.net/ ) which
can have multiple GUIs. Two of them seem to use the
/usr/X11R7/lib/modules/dri/r600_dri.so file eventually and crash in
them.
I think I saw something similar (at least involving dri, but with a
different crashing function) before in abiword, in PR 50320.
http://gnats.netbsd.org/50320
Fortunately VICE also has an Xaw GUI and that one works fine.
Do these stacktraces below ring a bell for anybody?
Here is a crash for the SDL2 GUI. This happens a few seconds after
starting up, and after some of the emulated screen has been shown
already:
Program received signal SIGSEGV, Segmentation fault.

Here is the same thing with GTK GUI:
