Hi,
I tried to have a look at it ...
Though, I'm too tired to be verbose, please refer to the pdf.
First a minimal, then some debugging output with a probably
significant difference.
Currently I've no idea for a fix, though.
\version "2.19.82"
\include "lyric-syllable-magnetic-snap-orig.ily"
\markup
\box \fill-line { minimal }
\new Lyrics

foo8 -- bar
_4
one2 --
\break
two1 -- three
}
good =
\lyricmode {

foo8 -- bar
one2 --
\break
two1 -- three
}
bad =
\lyricmode {
%% !!!!!!!!!!!!!!!!
