I debugged it some more, adding putStrLn’s in various locations. It
seems it crashes when parsing the packages files, which lead me to the
hypothesis that the problem is related to the happy-generated-files.
These files are generated by upstream with -agc. I re-generated them
without any special options, and the problem changed a bit: Instead of a
strange closure type, I now get a segmentation fault, but at the same
position:

I don’t know where to continue from here (and it’s too late), but maybe
someone else has a nice idea now.
BTW, is there a corresponding upstream bug? I didn’t find one.
Greetings,
