Do you have lang/clover installed? If so darktable is not gracefully handling opencl invocation. In current DRM driver implementation we do not support /dev/dri/renderD128+ nodes that do not require X11 authentication (mesa developers removed x-cookie verification from clover and to add it back is not so trivial). We could add /dev/dri/control and /dev/dri/render nodes into drm.ko (technically we should anyway) but that would open up a very likely security hole. Given how most of c++ programs deal with OpenCL contexts we would also need swapable drm/ttm buffer memory too and that is another story.
If it is lang/beignet on i915, just don't use it.

The first time I run "darktable", everything is fine. When I close it, and start it again, it fails with the following error:

    ld-elf.so.2: assert failed: /usr/src/libexec/rtld-elf/rtld.c:3045

    Signal 0

When I reinstall darktable (pkg remove darktable && pkg ins darktable), and then start it again, it works. But again, the second time, it fails with the same error.

This is my configuration:

    DragonFly babel.localnet 4.7-DEVELOPMENT DragonFly v4.7.0.1064.g9294ae-DEVELOPMENT #14: Wed Dec 28 14:45:50 CET 2016
        mneumann at babel.localnet:/usr/obj/usr/src/sys/X86_64_GENERIC  x86_64

I am using radeonkms. Is something corrupting my memory? Maybe OpenGL?
