Ok, I've been `git bisect`ing darktable this morning.  I'm using a
script `retry` to automate the repeated compilation (attached).

The result being

    $ cp /home/sk/foto/20180923-000/DSC_3932.NEF ~/tmp
    $ cd ${darktable_source}
    $ git clean -xdf

    $ ~/prg/darktable-tools/retry master # bad
    $ ~/prg/darktable-tools/retry release-2.4.4 # good

[...]

    $ git bisect good
    Bisecting: 2 revisions left to test after this (roughly 1 step)
    [92c1733369600cb034852676124026479aa69c83] fix cross position
    $ ~/prg/darktable-tools/retry
    $ git bisect bad
    Bisecting: 0 revisions left to test after this (roughly 0 steps)

    $ ~/prg/darktable-tools/retry
    $ git bisect good
    92c1733369600cb034852676124026479aa69c83 is the first bad commit

I do not understand this code, but I've posted this info on
darktable's bucktracker [1].

Now I'll start bisecting FVWM...
