In case of crash always look for the following (or similar, if abort()
is called)

#6  <signal handler called>

then the strack below has what functions were called in what order.

Second thing is message printed right before the crash:

(well, informative, right? Basically, the metaengine doesn't have a
callback for that particular class, if I understand correctly. Anyway,
shouldn't it throw an informative exception instead of asserting and
failing? That makes me look at the MetaEngine in a closer way...:

Interesting is the generated .xml file at that place
(Preprocessor('MembraneTest').generate('/tmp/a.xml'))

    <initializers _className_="InteractingGeometryMetaEngine"  label=""
functorNames="[]">
                <functorArguments size="0" />
    </initializers>

No functores? Why is this line commented out?

  //
interactingGeometryDispatcher->add("ef2_BshTube_BssSweptSphereLineSegment_makeBssSweptSphereLineSegment");

Re-enabling this line makes me run without crash :-)

PS. You really _want_ to use those ugly names of classes? OMG... at
least skip the _make part and write just _BssSweptSpheres..., no?
