Great! (Well, I am happy to see that the problem wasn't only
occuring in my own setup, since I would then be even *more*
stumped than I am currently.  :-)  Now that the problem has
been confirmed elsewhere I feel much better about the whole
thing. Then again, I feel sorry for causing a delay in the
1.2 release. Oh, well, the things is pretty serious...)

Hmm. How many threads are doing work in the subsequent runs?

Indeed...

As an added data point (not exactly new, but anyway), I can
have the problem occur in a multi-pipeline setup as well, in
which I have two pipelines doing initial processing for two
separate incoming data-sources, and when done they both call
a third pipeline for common processing. I have had the crash
occur in the third, common, pipeline. So, the problem travels
across Call-stages as well. FWIW.

I am available (during Swedish working hours, at least) for
running more or less whatever tests anybody can come up with
that are worth running, if it helps. I can do and test code
changes as well, as long as I can grasp what they intend to
do. :-) Right now, I feel that I have put in synchronization
both here and there to no avail, so I am *obviously* missing
the target. Hints to get me on the right track are welcome!
