Can anyone with more knowledge than me give me a hint what's wrong?
IIUC correctly, lilypond draws a bar line at the beginning of each line,
but in most cases, this is an invisible one.
If you look at the results of input/regression/lyrics-spanbar.ly,
the whole stuff is shifted that much to the right that lilypond moves
the rightmost rest to a new line! I can't believe that a bar line with
zero width can be the cause for this...
Any hints are highly appreciated!

Hey Marc,
I unfortunately don't have much time to help you out, but I can tell you that
you are on the right track doing prints to the command line. I would not,
however, stash them in lambda functions used as overrides, as this can
sometimes interfere with pure properties.
There are a couple classic things I use, most of which are in grob.cc.
In Grob::pure_relative_y_coordinate, before the last return statement, you can
put:
if (name () == "BarLine") print ("RELATIVE COORDINATE for BARLINE at spanned rank
%d: %4.4f\n", spanned_rank_interval ()[LEFT], out);
