Okay, the segfault in jack_capture has been fixed. I
had screwed up the handling of jack shutdown. New
version of jack_capture is uploaded.

I think though, that the reason jack shut down in the
first place, is because of a bug in jack. I don't know
the status of that situation. Perhaps someone on the
jack list can say something about whether it has
been fixed.
